Air-Cooled EO Q-Switched Laser

The Lapa series lasers are a new generation of air-cooled, DPSS  lasers.They offer fundamental energy output of 100mJ, repetition rates from 1-20Hz, and pulse widths of less than 10ns. Frequency doubling to 532nm, tripling to 355nm, and quadrupling to 266nm are available options. These products feature excellent long-term reliability and environmental adaptability, making them ideal for applications such as LIBS, LiDAR, and panel laser repair.

This series employs uniform pumping technology, conduction cooling technology, and DC power supply, among other innovative solutions, making it a truly portable nanosecond laser source. Suitable for 24/7 continuous operation, it provides new solutions for scientific, industrial, and military applications.
