Air-cooled Q-switch QS080-2G-3D1
Air-cooled Q-switch QS080-2G-3D1
DPSS systems, polarisation insensitiveMiniature size, conduction-cooled1.0mm active apertureGooch & Housego present probably the smallest, conduction-cooled, acousto-optic Q-Switch currently in production anywhere in the world. Specifically designed for use in miniature, short-pulse, low power, DPSS lasers, the tiny size of this device facilitates Q-Switching of the shortest cavities.
Utilising a highly efficient crystalline interaction material, greater than 85% loss modulation can be achieved without the need for active cooling - just bolt the Q-Switch to the laser rail and switch on!
Operating at 80MHz carrier frequency, the diffracted beams are sufficiently separated for most short cavities and pulse repetition rates of 100kHz or more are possible.

Application Notes:
The surface should be kept clean and dry. If the surface is contaminated, the surface will easily be burnt due to high power laser beam.The cooling water should be de-ionised water or distilled water. Please do not use city water as cooling water. Otherwise, the cooling channels will be corrupted and then the Q-switch will be damaged.The damage caused by non-proper use is not within the warranty.Air-cooled Q-switch QS080-2G-3D1
