 The laser must have the above three parts, the pump source , the working material and the optical resonant cavity, and the laser using solid laser material as the working material. The working substance undergoes population inversion distribution under the action of the pump source and becomes an active substance, which has the effect of light amplification. Part of the amplified light is fed back to participate in excitation, and the resonant cavity oscillates, and laser light can be produced after certain conditions are met. 1. Pump source: its function is to give energy to the working substance, and to excite atoms from low energy level to high energy level of external energy. Usually there can be light energy, thermal energy, electric energy, chemical energy, etc. 2. Working substance: At the core of the laser, only the substance that can achieve energy level transition can be used as the working substance of the laser. 3. Optical resonant cavity: make the stimulated radiation...

Advantages of  355nm UV laser  marking machine Ultraviolet laser marking machine has the characteristics of short wavelength and small spot. It adopts 355nm laser, which is the first choice for high precision laser engraving machine and marking machine. Ultraviolet laser marking machines are known as “photo-etching” effects. High-energy ultraviolet photons directly destroy the chemical bonds of materials by “cold treatment”, and the processed parts have smooth edges and minimal carbonization. In addition, UV laser energy can be effectively absorbed by most materials and has good focusing performance, so it can be finely micromachined in a small space area, which has very high research value and broad application prospects. In layman’s terms, all lasers are excited by their working medium and excited to an excited state. Some photons (atoms) are on a low-energy step called metastable state. The higher the absorption energy, the higher the energy level step, and the const...

Analysis on Demand Growth of Ultraviolet Laser Industry The output wavelength of the ultraviolet laser is below 0.4 μm, which is characterized by short wavelength, concentrated energy, and high resolution. Infrared or visible light is usually processed by means of concentrated localized heating to melt or vaporize the material. However, this heating can cause severe damage to the surrounding area, thus limiting edge strength and the ability to produce small, fine features. Ultraviolet lasers are chemical bonds that directly destroy the atomic components of the connecting substance. This process of separating matter into atoms is a “cold” process that does not produce heating to the periphery. On the other hand, most materials can effectively absorb ultraviolet light, which can be used to process materials that cannot be processed by infrared and visible lasers. Therefore,  ultraviolet lasers  have a great advantage in processing metal materials (especially surface treatme...
