The fastest knife! 355nm integrated and split UV solid-state lasers

The importance of laser is self-evident, it can be widely used in industry, medicine, communication, military and other fields, and promote the process of social development. Therefore, some people call it another important invention of mankind after nuclear energy, computers and semiconductors since the 20th century. At the same time, it is also known as "the fastest knife", "the fastest ruler" and "the brightest light".

Light is when electrons in atoms absorb energy, transition from low energy level to high energy, and then fall back from high energy to low energy, and are released in the form of energy photons released when they fall back. The laser is the photon array that is induced (excited), and the photons in this photon array have the same optical properties and are extremely consistent.

355nm integrated and split UV solid-state lasers. According to the use environment, this series of products can be water-cooled and air-cooled, with stable product performance, compact structure and low power consumption, which can meet the needs of industrial precision processing. The output laser is the fundamental mode, with good beam quality and high peak power.

The laser must have the above three parts, the pump source, the working substance and the optical resonator, and the laser using solid laser material as the working substance. Under the action of the pump source, the working substance undergoes a population inversion distribution and becomes an activated substance, which has the effect of light amplification. A part of the amplified light is fed back to participate in the excitation, and the resonator oscillates. After certain conditions are met, laser light can be generated.

1. Pump source: its function is to give energy to the working substance and excite the atoms from the low energy level to the external energy of the high energy level. Usually there can be light energy, thermal energy, electrical energy, chemical energy and so on.

2. Working material: The core of the laser, only the material that can achieve energy level transition can be used as the working material of the laser.

3. Optical resonator: make the stimulated radiation of the working substance continue; continuously accelerate the photons; limit the direction of the laser output.

With the further popularization and application of laser technology, in order to meet the various needs of lasers in the market, lasers will gradually move towards serialization, combination, standardization and generalization.

With the gradual upgrading of technology in the laser industry, the applications in the electronic manufacturing industry, communication industry, integrated circuit industry and other fields will continue to expand in the future, and the market demand will also gradually increase.

In the future, industrialized products will only move in the direction of convenience and integration. The same is true for lasers, which are small in size, light in weight, integrated with circuits and optical paths, high in power and good in stability. Therefore, high-power integrated models have become inevitable. development trend.
