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.
