The electro-optic deflector makes an ideal Q-switch for compact, low average power systems. Polarizers are not required and the optical loss can be kept to below 1%.
The ability to deflect in a few nanoseconds allows short Q-switch pulses to be produced and high repetition rates obtained.
The 1 mm aperture deflector has been successfully used to Q-switch a micro-chip laser at 20kHz while producing 1.5 ns pulse lengths.
Leysop can supply the deflector with a miniaturized 1kV driver operating between 0 – 20 kHz. The Q-switch is not liquid filled and does not require accurate alignment.
