41/68/80MHz Q-switches

1. 41MHz Acousto-optic Q-switches

A compact, conduction-cooled, acousto-optic Q-Switch for use in DPSS Nd:YAG & Nd:YVO4 lasers. Utilising the same manufacturing technology as our industry standard, high power QS24/27 series, these compact devices offer unrivalled reliability through superior optical quality and coatings.

Optimised for use with linearly polarised beams of up to 1.6mm diameter, offering loss modulation figures exceeding 85%. Utilising Crystal Quartz as the interaction material to give increased efficiency and high thermal transfer properties allowing use at RF powers of up to 15W, conduction-cooled.

This Q-Switch can also be customised to feature alternative frequencies, active apertures and housing designs, our team of scientists will be pleased to discuss variations with you.

• DPSS Nd:YAG / Nd:YVO4, linearly polarized

• Compact conduction cooled, crystal quartz

• 2mm active aperture

2.68MHz Acousto-optic Q-switches

3. 80MHz Aousto-optic Q-switches

We 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. - DPSS systems, polarisation insensitive - Miniature size, conduction-cooled - 1.0mm active aperture

Ultra Compact Conduction Cooled 80MHz Q-Switches

I-QS080 is an ultra-compact conduction-cooled Acousto-Optic Q-Switch, ideally suited to short cavity end pumped Nd:YAG & Nd:YVO4 lasers. Utilising top grade Crystal Quartz for increased efficiency & thermal stability, with high quality optical finishing & high damage threshold antireflection coatings to provide high damage threshold & low insertion loss.
