Green Laser

Ultra-compact High reliability High stability High efficiency Low noise

CrystaLaser designs and manufactures state of the art ultra-compact diode-pumped green laser systems. Our green lasers feature with high reliability, high stability, high efficiency, low noise and excellent laser beam quality.

The solid-state DPSS green laser products including DPSS CW green laser and DPSS Q-switched green laser systems. The SHG of Nd:YAG, Nd:YLF, Nd:YVO4 green lasers with true CW output and Q-switched pulsed output are for industrial instrumentation applications in holography, biomedical, fluorescence, reprographics, laser trapping, laser Raman, interferometry, semiconductor inspection and materials processing.

New green laser products:

515 nm and 488 nm dual wavelength laser outputs up to 150 mW as Argon ion laser replacement in a compact laser housing with low power consumption.
532 nm green laser outputs 1W in a compact laser housing.
100 mW yellowish green laser at 542 nm; up to 500 mW greenish yellow laser at 561 nm and 555 nm.
Ultra-stable CW green laser, laser output stability 0.5% and 0.25% over 24 hours, is available now.
Compact Q-switched Green lasers at 532 nm, 523 nm, 527 nm, 542 nm, 555 nm and 561 nm are available now.
Up to 250 mW, single longitudinal mode, 532 nm green laser with more than 300 meters coherence length is suitable for holography, interferometry and laser Raman applications.

The green laser is easy to use, plug and play, no cooling fan, no cooling water required, no noise and no vibration during laser operation.

The diode-pumped green lasers are based on our proprietary coupled-cavity laser technology. This patented laser technology allows our green lasers to operate in a single longitudinal mode and TEMoo mode with low amplitude noise and extremely low power consumption in a compact laser housing.
