HQD-FP Series Diode Pumped Q-switched Laser
HQD-FP Series Diode Pumped Q-switched Laser

HQD-FP series lasers are RealLight’s self-developed, passively Q-switched diode-pumped solid-state lasers. HQD-FP series utilizes a split-cavity design, delivering high power, high repetition rate and large energy, with standard wavelengths of 1064nm and 532nm. Beam expanders and other customized specifications are available upon request.

1. Beam expanders are an optional part and are not included by default unless otherwise noted.
2. Temperature control is required for laser head during operation. The temperature of the base plate should be controlled at 15-35℃.
3. As products are constantly being updated, the right of final interpretation of technical specifications or illustrations in datasheet belongs to RealLight.
