Designed for illumination purposes on Particle Image Velocimetry (PIV), OptoDP DUAL series laser comprises two high efficiency DPSS side pumped cavities with intracavity frequency doubling. Cavities are mounted in compact monolithic housing and the laser beams are combined on the output by polarizers.
Features:
- Two independent laser channels with adjustable pulse repetition rate and output power
- 19” rack mounted laser control units
- Air-water chiller
- PC control
Options:
- Variable beam expander for adjustment of size and divergence of the output beam
- Various laser wavelength combinations: 532 + 532 nm, 532 + 1064 nm, 1064nm + 1064nm
- Improved beam quality (М2<15)
