Infrared laser rods have extremely high optical power, and their power and efficiency have now reached a whole new level. Also of note is the blue wavelength laser rod, which can reach optical powers of up to 100 watts (W) in the lab, a huge leap forward.

According to the different time-domain characteristics of laser output, fiber lasers can be divided into pulsed fiber lasers and continuous fiber lasers. Different types of fiber lasers have different typical applications in the industrial field.

Optical fiber is a kind of fiber made of glass or plastic, which uses the light transmission tool to transmit light in these fibers by the principle of total internal reflection. It consists of a fiber core, cladding and protective sheath.Optical fibers can be divided into single-mode optical fibers and multi-mode optical fibers.

In recent years, my country's laser industry has developed rapidly, especially in the field of domestic fiber lasers. Many businesses are pushing 10,000-watt pigtailed lasers.

most VCSELs are based on gallium arsenide semiconductor, and the emission wavelength is mainly in the near-infrared band. It is a laser that emits laser light perpendicular to the surface of the substrate. Multiple lasers can be arranged in multiple directions on the substrate to form a parallel light source or an area array light source. It is one of the main light sources in the field of optical fiber communication or optical sensing.

The so-called laser technology is a general term for exploring and developing various methods of generating lasers and exploring and applying these characteristics of lasers for the benefit of mankind.

In the light source, the realization of energy level population inversion is the premise of realizing light amplification, that is, the precondition of generating laser light.

Laser is a kind of light that does not exist in nature and is emitted due to excitation. It has the characteristics of good directionality, high brightness, good monochromaticity and good coherence.

Semiconductor lasers, also known as laser diodes, are lasers that use semiconductor materials as working materials. It has the characteristics of small size and long lifespan, and can use simple injection current to pump its working voltage and current compatible with integrated circuits, so it can be monolithically integrated with it. Due to these advantages, semiconductor diode lasers have been widely used in laser communications, optical storage, optical gyroscopes, laser printing, ranging and radar.

In recent years, market demand has promoted the development of technology. Nowadays, when electronic products are becoming more and more refined, traditional soldering iron welding and wave soldering can no longer meet the welding of all electronic products.
