A key factor in determining if a material can be cut is the level of the absorption of the material to 1µm laser light.
Fiber laser cutting ceramics.
Analysis of laser cutting materials fiber laser cutting effect structural steel.
The co2 laser can also engrave on glass ceramic stone and coated metals such as anodized aluminum or coated metals.
When oxygen is used as a processing gas the cutting edge is slightly oxidized.
Cutting alumina ceramic using professinal industrial laser s laser cutting system is accurate within just a few microns and faster than any other method of ceramic cutting.
Ceramic is usually separated with the help of pulsed solid state lasers or co 2 lasers and performances between 1 and 600 watt for sublimation cutting.
As the cutting depths in one cycle single pass is often only within the range of a few 10 micrometers higher material thicknesses are separated in the so called multi pass process.
For certain ceramics either a co 2 laser or a fiber laser can be used to create a visible mark without removing a significant amount of material.
The two most common cutting techniques are.

The pulsed fiber laser can also be used to cut a wide range of non metallic materials such as plastics and even rubbers.
The process produces a very high quality cut and although not essential post processing is recommended to enhance the quality yet further.
Laser processing of ceramics is typically performed using a 10 6 or 9 3 micron co 2 laser with some ceramics also absorbing a 1 06 micron fiber laser wavelength.
Changing cut patterns.
Laser cutting of thin film ceramic is also possible using a co 2 laser producing a clean edge with little discoloration.
A fiber laser basically does what a co2 laser cannot.
Two types of lasers are ideal for cutting ceramic.
The material will get better results when it is cut with oxygen.
Laser engraving of ceramics is achieved using a co 2 laser.
Using a fiber laser also allows aln ceramic to be cut in its green state before the material is fired.
Laser marking can be used to convey information such a serial number or a logo.
You can also use femtosecond lasers which offer superior cut quality and precision.
The fiber laser is used for marking or engraving bare metals and marking plastics.
Bright fiber lasers 1064 nm wavelength and high powered co2 lasers 10600 nm wavelength work well with ceramic and provide fast cutting.
Meta laser cutters are available in 150w 250w 400w and 1000w co2 lasers.
Cutting ceramic with coherent s meta laser machine tool.
The laser energy darkens the ceramic creating a sharp well defined mark.
