Fiber coupled blue lasers
Ultra-stable CW blue laser, output stability 0.25% over 24 hours
Blue laser with fast modulation up to 200MHz option is available
Compact Q-switched blue laser available now

Wavelengths of the blue lasers: 473, 375, 405, 390-415, 420, 430, 440, 442, 456, 462, 473 and 488 nm, 430 and 490 nm

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

The compact blue lasers are based on our proprietary laser design technology. This new technology allows our blue crystal lasers to operate in TEMoo mode with low amplitude noise and extremely low power consumption in a compact laser housing.
