### YAG Laser Cutter

YAG laser cutting machine is a solid laser cutting system based on yttrium aluminum garnet crystal. The chemical formula of yttrium aluminum garnet is Y3Al5O15, referred to as YAG. Like other solid-state lasers, the basic YAG laser components are working substance, pump source and resonant cavity.

Due to the different types of active ions doped in the crystal, the different pumping sources and pumping methods, the different structures of the resonant cavities used, and the different functional structural devices used, YAG lasers can be divided into many types. According to the output waveform, it can be divided into continuous wave, repeated frequency and pulsed YAG lasers. According to the laser wavelength, it is divided into 1.06μm, frequency doubling, Raman shift and tunable YAG lasers. According to different doping, it can be divided into Nd:YAG lasers and YAG lasers doped with Ho, Tm, Er. According to the shape of the crystal, it can be divided into rod-shaped and slab-shaped YAG lasers. According to different output power, it can be divided into high power, medium power, and low power YAG lasers.

YAG laser cutter expands, reflects and focuses the pulsed laser beam with a wavelength of 1.06 μm, radiates and heats the surface of the material, and the surface heat diffuses to the inside through heat conduction, and the width, energy, peak power, repetition frequency and other parameters instantly melt and vaporize the material, so that the cutting of the predetermined trajectory can be realized through the CNC controller system.

There is no problem of tool wear and replacement in cutting, no mechanical change, and easy-to-realize automation, and processing can be realized under special conditions. High pump efficiency, up to about 20%. With the increase in efficiency, the heat load of the laser medium decreases, so the beam is greatly improved. Long quality life, high reliability, small size, lightweight, suitable for miniaturized applications.

#### Cons

• Low photoelectric conversion efficiency and high cost of use;

• There is an internal temperature gradient in the YAG laser rod during the working process, which will cause thermal stress and thermal lens effect, which limits the further improvement of the average power and beam quality of the YAG laser;

• The maintenance of the YAG laser is troublesome, the structure is complicated, and The cost is also relatively high.

• The structure is complex, the power supply is large in size, and requires an optical path to work.

### Fiber VS Nd: YAG Laser Cutting Machine

Your choice between the Fiber laser and Nd: YAG laser cutting machine depends on your needs and the materials you are working with, since each of these technologies features certain strengths and weaknesses, making them appropriate for specific uses. Here's a detailed look into their differences that will help understand which is best for the task.

Fiber lasers are modern developments made with efficiency, speed, and low maintenance in mind. This works particularly well in cutting metals such as steel, aluminum, and copper. That is why it has become an industrial favorite when it comes to metal working.
