RealSubns® MCH Series 300ps SLM Microchip Laser
RealSubns® MCH Series 300ps SLM Microchip Laser

MCH series RealSubns® Single longitudinal mode(SLM) microchip lasers are compact, economical and reliable semiconductor pumped(diode pumped) passive Q-switch(passively Q-switched) solid state lasers independently developed by Reallight, with stable output energy, high peak powers and excellent beam quality. The monolithic laser cavity is permanently aligned, therefore extremely stable.

The system supports internal trigger and external trigger. This series of products produce the Single longitudinal mode 1064nm, 532nm, 355nm  and 266nm radiation with a long  lifetime. The pulse duration(pulse width) can go down to 300ps(0.3ns). Various models operate with repetition rates up to 100kHz and the average power ranges from 30mW to 100mW. The reliable and robust microchip design is perfect for advanced OEM industrial applications. For more information, please view our website: or write emails to:
