Crystal Metallization & Welding Services
Crystal welding refers to the welding and fixing of the working substance to the corresponding heat sink in the laser with a special process, which is intended to replace the traditional mechanical crimping method, in order to improve the heat dissipation effect of the working substance and reduce the crystal thermal lensing effect, so as to solve the problems of light and light conversion efficiency and spot quality. Oriental-laser provides welding services between laser working substances represented by YAG, YAP, YLF, LN, etc. and heat sink materials such as aluminum, copper, titanium alloy
Advantages
◆ Good heat dissipation: General crystal conduction heat dissipation by cushion indium foil with mechanical contact to heat sink always have gaps, not as good as indium welding heat dissipation. Indium welding crystal and heat sink is close contact with good heat dissipation. ◆ The crystal stress is small: Generally mechanical method is pressed on the heat sink structural parts, which is not easy to grasp the strength, and it is easy to lead to crystal deformation and beam quality when tight pressed, so the pressure is loose, but the impact vibration is easy to fall off if pressure is loose. While there is no such kind of problem by Indium welding crystal. ◆ Save structural space: Indium welding saves space and reduces the weight of the laser, it eliminates the space and weight required to mechanical method, and also reduces the length of the crystal, which is important for small lasers.

Application:
Indium crystal welding is generally used in ultra-small conduction-cooled or air-cooled solid-state lasers, especially suitable for the design and application of small airborne, unmanned aerial and space borne.
Product Advantages
Our core products are diode lasers and diode side-pumped gain modules. Over the years, we have been committed to continuously optimizing the gain module manufacturing technology from various perspectives such as module structure design, heat dissipation process, packaging process, array arrangement, etc., to provide stable, reliable and excellent performance side pump modules for many customers. Gain modules are divided into continuous CW modules and pulsed QCW modules. Among them, QCW module also includes conduction cooling module and water-cooling module. GN series continuous working module power is optional from 35W-450W; The maximum energy storage of GQ and JQ series pulse modules can reach 8J; The crystal diameter is optional from 2mm-25mm, and the conventional crystal material is ND: YAG; other crystal diameters or materials can be customized also.
