Laser Optics

 
Focus Lens
All use CVD Znse, imported from USA. Materials absorption is lower, lens can stand with high power density, and surface is firm, not easy to fall off, resistance to wipe.

Zinc selenide focus lens are widely used in CO2 laser process, including cutting, drilling, carving & other laser system. With the imported material, our products can withstand high power density; and the film is solid, with which the lens are resistant to wipe. Because of the double-side film, the filterability of the light (the wavelength is 10.6μm) can reach 99%.

Reflective Mirror

CO2 Laser Mirror

Reflect mirror is one of the most important elements in light transmission system, it can be used as tail mirror and folding mirror in laser cavities, outside the cavities, it plays the role of light-bent machine. Mirrors can be made by various materials. laser optics, laser optical, laser optics equipment

Mo mirror can be used in harsh environment, also for a long time, can stand high-power and resistant to wipe, but the reflectivity is not so high.

Silicon is used most as the material of mirror, it cost lower, durable, and with stable thermal properties. With gold plated and protection film on the gold, the surface is difficult to be damaged, it also enhance the reflectivity and durable. The fold-plated silicon mirror can stand high –power irradiancy.

Rods

In all laser equipment laser rod acts as a very important role. Whether in industrial, medical laser equipment or military laser equipment. Laser rods play a very important role.
Nd: YAG is cubic crystal, it is isotropic crystal. Nd: YAG is a four-level system, high quantum efficiency, broad stimulated emission area, so the threshold is much lower than ruby and neodymium glass. Also, because the Nd: YAG crystal has excellent thermal properties, it is ideal crystal for continuous and heavy-frequency devices. Nd: YAG crystal is able to work continuously at room temperature, the only solid working substances in low and medium-power pulse devices, the current application of Nd: YAG is much more broader than any other substances.

Nd: YAG ROD is the most mature and widely used as solid-state laser material, adopted by R&D, medical, industrial and military customers. Its main and obvious advantages are: high gain, low threshold, high efficiency, low loss at 1.064 μm, as well as high optical quality, good thermal conductivity and thermal shock characteristics, stable chemical and mechanical properties, which make Nd: YAG as the most suitable and commercial laser material for various modes of operation (CW, pulsed, Q-switched, mode locked and cavity dumped).
