Application of different lasers in desktop engraving machines

There are also dozens or hundreds of categories of lasers. However, there are not many types of lasers used in the field of desktop consumer grade laser engraving machines.

In summary, there are mainly the following categories:
1.A semiconductor blue laser with a wavelength of 455nm
2.Infrared fiber laser with a wavelength of 1064nm
3.MOPA laser with a wavelength of 1064nm
4.CO2 molecular laser with a wavelength of 10.6um
5.Ultraviolet laser with a wavelength of 355nm
6.Green laser with a wavelength of 532nm

Part 1 455nm semiconductor blue laser

The main application scenarios of semiconductor lasers are:
Suitable for non-metallic cutting and marking, can be applied to dark opaque acrylic, but not to transparent acrylic. At present, it is mainly used in wood carving and cutting, as well as common paper, leather, medium density fiberboard, bamboo, fabrics, dark glass, etc. in daily life.

Part 2 1064nm Infrared Fiber Laser

The main application scenarios of fiber lasers are: mainly used for engraving metal materials such as stainless steel, carbon steel, aluminum and alloys, copper and alloys, titanium and alloys, and can also be compatible with some non-metallic materials and composite materials. The materials that a laser can be applied to mainly depend on its absorption rate for lasers of different wavelengths. Similarly, the reflectivity and thermal conductivity of materials directly affect the effectiveness and difficulty of laser processing.

Part 3 MOPA Structure Laser

The main application scenarios of MOPA structured lasers are:
It can achieve blackening of anodized aluminum, color marking of stainless steel, and higher precision processing. Relatively speaking, its cost will also be higher than that of Q-switched fiber lasers.

Part 4 10.6um CO2 Molecular Laser

The main application scenarios in the desktop consumer and Small Bussiness fields are suitable for non-metallic cutting and marking, which can be applied to transparent acrylic cutting

Part 5: 532nm Green Laser and 355nm UV Laser

The main application scenarios of ultraviolet lasers are:
In theory, it is suitable for most metal and non-metal materials, and belongs to cold processing with high precision. In fact, it is more suitable for processing non-metallic materials such as plastic and glass, and can now achieve glass carving, further expanding its application scenarios. Due to the current high cost of ultraviolet lasers, the power used is not high, usually 5W, mainly suitable for marking scenarios.

Part 6 Dual Laser Fusion

This year, there are gradually emerging other forms of 2-in-1 products in the market, such as Blu ray+MOPA, UV+MOPA, etc., which are essentially the concept of all-in-one products.
