Diode-pumped short-pulse passively Q-switched solid-state laser
The Locmar series is an LD-pumped passively Q-switched short-pulse solid-state laser (DPSS) with output wavelengths ranging from near-infrared to ultraviolet. The single pulse energy can reach up to 300µJ @ 1064nm, with a pulse width of approximately 2ns. The laser utilizes air cooling or conduction cooling, requiring no water and being maintenance-free.
This series is primarily used in applications such as MALDI-TOF mass spectrometry, LiDAR, and LIBS. The Locmar series features a compact design, making it ideal for OEM customers' system integration. Additionally, the laser head employs an optoelectronic separation design, with optical components treated for solidification, ensuring long-term stable operation.
