Types of laser device:

There are different classification methods for lasers, which are generally classified according to different working media, and can be classified into solid lasers, gas lasers, liquid lasers, and semiconductor lasers.

 

1. solid state laser

In general, solid-state lasers are characterized by small size, robustness, ease of use, and high output power. The working medium of such a laser is uniformly doped with a small amount of activating ions in a crystal or glass as a matrix material, which emits a near-infrared laser of 1060 nm.

 

2. gas laser

The gas laser has the advantages of simple structure, low cost, convenient operation, uniform working medium, good beam quality, and continuous operation for a long time. This is also the most widely used and widely used type of laser, which accounts for about 60% of the market.

 

3. Semiconductor laser

A semiconductor laser is a semiconductor material as a working medium. At present, a more mature one is a gallium arsenide laser that emits a laser of 840 nm.

 

4. liquid laser

Commonly used are dye lasers, using organic dyes as the working medium. The working principle of liquid lasers is more complicated. The output wavelength is continuously adjustable, and the coverage width is its advantage, making it widely used.
