What materials Cannot be cut by a laser?
- Leather and artificial leather that contains chromium (VI)
- Carbon fibers (Carbon)
- Polyvinyl chloride (PVC)
- Polyvinyl butyrale (PVB)
- Polytetrafluoroethylenes (PTFE /Teflon)
- Beryllium oxide.
Laser cutting is so popular largely because of its versatility. Laser cutters can cut a wide variety of materials – anything from paper, wood, cork, acrylic and foam to different types of metals.
Although polyvinyl chloride (PVC) can in fact be cut with laser, the thermal process produces hydrochloric acid and toxic fumes. For this reason, we advise you not to use laser for cutting PVC in order to prevent corrosion of your laser system and to ensure the safety of the machine operator.
Of course, laser machines can also be used to cut rubber, not just engrave it. This is a thermal cutting process in which the shapes are traced by a precise laser beam using predefined patterns and the material is cut through.
Lasers can cut through many materials and are typically used on a select few types of metal — in particular, carbon steel, mild steel, stainless steel, steel alloys and aluminum. Carbon steel: Steel is a mixture of iron and carbon.
So, now we know that yes lasers can cut diamonds and it is needed. The price and quality of diamonds depend on their shape so not any kind of laser cutter should be used while cutting diamonds. Established and branded lasers not only provide ease in work but also offer a quality product.
Lasers can cut glass of varying thickness to just about any shape. Quick, clean, accurate and adaptable, laser cutting is the preferred method for many businesses across a wide range of industries. Industrial laser cutters can cut: Any Shape Imaginable with the Highest Flexibility.
In summary, in almost all industries and areas of application, MDF, plywood and veneer are the most popular types of wood for laser cutting. These types of wood are most suitable for laser engraving and laser cutting.
Laser processing of fiberglass sheet is possible with a 9.3 or 10.6 micron CO2 laser, with no significant difference in quality produced by the two wavelengths. The 1.06 micron fiber laser is not used for processing this material as the wavelength is not readily absorbed.
Glass mirror can't be laser cut
It is not possible to laser cut glass with Co2 laser machines. It is best to have it supplied to us pre-cut to size by a glazier / glass cutter.
Can I cut silicone with a laser?
Laser cutting of silicone rubber can produce a smooth, clean edge on material up to 0.25 inches thick (6 millimeters). Laser engraving of silicone rubber can produce deep engraving while maintaining high detail.
For metal based foams, a Fiber laser is most effective. The Fiber laser can cut through thin sheets of foam (up to 1/8” or 3 mm). Ceramic based foam is not usually cut with a laser because it is very brittle and can crack.
Laser cutting of BISCO® Silicone Foam with a CO2 laser produces a sharp cut with a slightly charred edge which can be cleaned after processing. Laser engraving of BISCO® Silicone Foam with a CO2 laser produces depth with some debris on the surface which can be easily removed.
Laser can cut quite deeply into stone, if the design calls for it, says Siegel. Although it is also possible to cut completely through stone with a laser engraver, because the beam can only cut about 1/8 of an inch deep on each pass, it's really not practical for stone cutting.
While it is reflective, soft and thermally conductive, aluminum can still be cut with a CO2 or fiber laser. High-speed laser beams make it possible to cut various alloys of aluminum, including aerospace and marine-grade aluminum alloys.
Crack propagation is an especially significant concern for cast iron, and iron laser engraving is an excellent option for creating permanent marks on cast iron without compromising its physical integrity.
To say something is “hard” is not the same as saying it is “strong”. As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the hammer is strong. Whether something is hard or strong depends on its internal structure.
Diamonds are crystalline minerals and the only way to cut the stone is to split it along the weak crystal direction. The special blade comes in handy since some of the tiny diamonds will have enough strength to spilt the diamond along its tetrahedral plane, its weakest point.
After the light goes through the diamond, it speeds right back up again, and the different wavelengths disperse among the air. Due to the diamonds geometric prism-like shape, when the light exits, it creates a rainbow of colors much like the way a rainbow is formed from water vapors in the sky after heavy rainfall.
While there are some laser cutters that can cut material as thick as 20 mm, most machines work on materials closer to 0.5-12 mm thick, depending on what's being cut.
What can a 7 watt laser cut?
Next Wave Automation's 7 Watt Solid State Laser Module boasts enough power to engrave wood, leather, and acrylics as well as the ability to cut thin soft materials like balsa, basswood, foam, paper, and fabric.
Plywood requires high laser power to perform clean cuts with minimal burns along the edge of the cut. Generally, a CO2 laser with a power rating of around 60-100W is recommended for laser cutting plywood of various thicknesses. It is also recommended to use multiple passes at high cutting speed.
Melamine, which falls into the Phenolics category, does engrave nicely with lasers.

Laser Engraving of Plastics
The laser engraving process can be used to create intricate patterns and designs into the plastic surface.
Nylon does not readily absorb the energy from the 1.06 micron fiber laser and is not recommended for this material.
Laser Cut PVC, PVC Foam Board
Although these materials can be laser cut with our lasers, we avoid it as this process produces chlorine gases which is not good for the machinery or people, so we stay away from PVC.
Since lasers are beams of light, they will either be reflected or refracted when they hit a surface. If they are reflected, then these beams will bounce off of mirrors.
When a laser is shined on a mirror the mirror reflects, bounces, the light beam back. The angle that the laser enters the mirror is called the incident angle and the angle that the light exits the mirror is called the reflected angle.

What's the most powerful type of laser?
ZEUS Laser
ZEUS is the most powerful laser in the United States. It's actually designed to punch above its weight: while ZEUS doesn't deliver this much raw power, its design simulates a laser that is roughly a million times more powerful than what it says on the tin.
Laser can cut quite deeply into stone, if the design calls for it, says Siegel. Although it is also possible to cut completely through stone with a laser engraver, because the beam can only cut about 1/8 of an inch deep on each pass, it's really not practical for stone cutting.
The actual answer is no, it can't. Even a mirror that reflects 95% of a lethal laser beam will still absorb enough heat to burn. This causes the reflectivity to be gone almost instantly, but a scattered burst of light from the point of impact could still blind the shooter or his allies.
Laser is just another way to deliver such energy, since the a photon has enough energy to break some bonds and deliver some heat for the molecules that can evaporate. Since cutting is just breaking chemical bonds and removing particles in some specific place, laser has ability to cut.
As a general rule, green lasers are 532nm are 5-7X brighter than any other laser color, at the same power. Whether blue, red, purple/violet, or a light color like yellow, green is the best at strength for visibility.
Green light at 555 nanometers is the most visible (100%). Most green consumer laser pointers and handhelds emit 532 nm light. This is perceived as being 88% as bright, compared with the potential maximum (555 nm light). For red light at 633 nm, the eye sees it as only 24% as bright as 555 nm light.
It is directed to targets by the Phalanx CIWS radar. With tests going well, the Navy expected to deploy a laser weapon operationally between 2017 and 2021 with an effective range of 1 mi (1.6 km; 0.87 nmi).

Nylon Overview
Laser processing of nylon can be performed with a 9.3 or 10.6 micron CO2 laser. Nylon does not readily absorb the energy from the 1.06 micron fiber laser and is not recommended for this material. Laser cutting of nylon with a CO2 laser produces a clean edge with minimal melting along the cut path.
Can lasers burn underwater?
So, do laser beams actually work underwater? And the simple answer to that question is “yes,” they absolutely do. As long as the internal components aren't exposed to the water, they'll work just fine.
Actually, when two laser beams (or any other kinds of light for that matter) collide, they do not stop each other. In fact, usually they behave as though the other is not there at all. This is because light is a wave, and usually waves cross each other without interacting.
It should be noted that today it is possible to shine laser systems through walls, however, only very specific types of walls and probably the list of walls will increase very soon.
Laser Cutting Graphite - Fail - YouTube
Although used to produce parts in almost every industry, laser cutting does have it downsides. Namely, need of expertise, limitations to metal thickness, costs and hazardous fumes are all things to consider before turning to laser cutting.
The maximum cutting thickness of different materials by 1000W fiber laser cutting machine: the maximum thickness of carbon steel is 10mm; the maximum thickness of stainless steel is 5mm; the maximum thickness of aluminum plate is 3mm; the maximum thickness of copper plate is 3mm; 3.
