High-power lasers usually generate large amounts of heat, which can easily damage the laser tube for a long time. It is not recommended to use high-power lasers for a long time. Sometimes, the user needs to make the high-power laser work continuously for a long time. Is there any way? Figure 1. Without heat sink, can not work continuously for a long time We have summarized some experiences in actual work to share with you. 1. Select Laser Ask the merchant if the laser is with TEC when buying. TEC (Thermoelectric Cooler) is a semiconductor refrigeration chip, which is widely used in temperature control in various equipment. Figure 2. Heat sink and fan Laser working at high temperatures will cause damage to the laser tube, so it is also necessary to bring an overheating protection module. When the temperature rises to the limit of the laser tube, the laser must automatically stop working. 2. Do a good job of heat dissipation As long as the heat dissipation is done, t...

Abstract : According to the special structure of fiber laser, different types of fiber laser pump sources  are proposed, and the criteria for selecting pump source and its corresponding efficiency are given. The main components of the laser are the resonant cavity, the pump source and the working substance. The pump source is the excitation source that causes the laser working medium to reach the population inversion. The process of particles from the ground state to the high energy level is called the pumping process. Common pumping methods include electric pumping, chemical pumping, optical pumping, and pneumatic pumping, while optical pumping and electric pumping are the most widely used methods. Gas lasers often use an electric pumping method as an excitation source, and optical pumping methods are widely used in solid and liquid lasers. Optical pumping uses a beam of light to illuminate the working substance so that the particles in the working substance absorb the energy...

Solid-state lasers with all powers are very diverse. Asia has the fewest products, but it is growing rapidly. Among them, China is playing an increasingly important role. The future of industrial laser applications is limitless. Analysis of global industrial laser applications shows that laser cutting and laser marking are at the forefront. Followed by welding, micromachining and engraving. There are not many applications for laser drilling. Nevertheless, the development of the paper product processing market is promoting the promotion of laser drilling applications. In terms of the installation volume of industrial laser application systems, the increase in installations in China directly expands the share of installations in the Asian laser industry application system, which makes the installations in North America, Europe and Asia relatively flat, around 30%. . The continuous application of laser technology in the industrial field has promoted the development and even leap of the g...

1.  L aser working medium The laser  must be produced by selecting a suitable working medium, which can be a normal body, a liquid, a solid or a semiconductor. In this medium, particle number inversion can be achieved to produce the necessary conditions for obtaining a laser. Obviously, the existence of the metastable energy level is very advantageous for realizing the population reversal. There are nearly a thousand working media available, and the laser wavelengths that can be generated include the far infrared from the vacuum ultraviolet ray, which is very extensive.  As the core of the laser, it consists of activated particles (both metal) and matrix. The energy level structure of the activated particles determines the laser characteristics such as the spectral characteristics and fluorescence lifetime of the laser. The matrix mainly determines the physical and chemical properties of the working substance. According to the energy level structure of the activated...

Development history of  405nm blue-violet laser semiconductor laser The 405nm laser has advantages in many areas. This band is representative of the shortest wavelength range of visible light and is also the working band of HD HD DVD. The origin of the blue-violet laser 1. In the mid-1990s, blue-violet lasers appeared The development of blue-violet lasers originated from the development of a 400-410 nm gallium nitride crystal blue-violet laser semiconductor laser from Nichia Corporation in Japan in 1996 to further increase the storage capacity of DVD discs. Because of its shorter wavelength. The focus spot is smaller, the same size DVD disc is 40 times larger than the ordinary CD disc, 6-7 times the ordinary home DVD disc, but the laser power applied to the DVD is very small. With the continuous expansion of laser power, the blue-violet laser with a service life of more than 3,000 hours in 1999 was introduced. 2. Several major Japanese companies compete to produce blue-v...

Both 532nm and 520nm wavelengths are green laser sources, and the 520nm laser is a bit grassy green. But the principle of illumination of the two lasers is completely different: 532nm is dpss, and the inside is illuminated by a laser crystal. 520nm is a semiconductor laser, and inside is a laser diode.
