Acousto-Optic Q Switch
GSU-4 A-O Q Switch GSU-5 A-O Q Switch GSU-8 A-O Q Switch
Water Cooled Water-cooled Water cooled
 
      This is a kind of water-cooled acousto-optic Q switch mainly used in Nd:YAG laser system. The melted quartz blocks with very good optical feature and films with high penetrability are used, which optical character is very good. The cavity insertion loss is low and the anti-injury threshold is high.        This is a kind of water-cooled acousto-optic Q switch mainly used in Nd:YAG laser system.

GSU-6 A-O Q Switch GSU-7 A-O Q Switch
Air cooled Air cooled
    The Q switch is consisted of the device and the power supply and always uses in diode pumping solid-state laser for Q modulating. No water-cooling needed. The responding speed is fast and easy to control. Small size and good stability make it suitable to use in the diode pumping solid-state laser.     This kind of Q switch with double wavelength is made up with the device and the power supply and always uses in diode pumping solid-state laser for Q modulating. No need of water-cooling for the device. Responding speed is fast and easy to control. Small cubage and good stability make it suitable to use in the diode pumping solid-state laser.
