We design and manufacture state of the art ultra-compact diode-pumped blue laser systems. Our blue laser features with high stability, high efficiency, high reliability, low noise and excellent laser beam quality. These blue lasers are specificly designed for OEM, scientific and industrial use. The blue lasers are for the application in holography, biomedical, fluorescence, flow cytometry, replace Argon ion laser and He-Cd lasers.
Current available blue laser products including diode-pumped CW blue laser and Q-switched blue laser products.


488 nm blue laser outputs 50 mW in single mode circular beam.

50 mW, 405 nm, single longitudinal mode blue laser provides >50 meters coherence length and narrow linewidth
True CW Ultra-Violet (UV) single longitudinal mode laser at 375 nm up to 16 mW provides >50 meters coherence length and narrow linewidth
Low noise 50 mW, 488 nm and 70 mW, 473 nm blue laser and single longitudinal mode 20 mW 473 nm blue laser
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, 390-425, 445, 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.
