‘Industry Standard’ Acousto-Optic Q-Switch
A water-cooled Acousto-Optic Q-Switch for use in high power lamp or diode pumped Nd:YAG lasers. Combining top grade fused silica with high quality optical finishing and in-house anti-reflection coatings, this Q-Switch exhibits very low insertion loss and high damage threshold. It’s design characteristics and repeatable manufacturing process enable RF powers of up to 100W (for shear mode options).
Standard options include a choice of RF frequency (24 to 68MHz), active apertures (1.6 – 8.0mm), acoustic modes (compressional for linear polarisation, shear for random polarisation).Custom options, including alternative mechanical designs & wavelengths are available upon request.
Our engineers are available to assist in selecting the most appropriate model of Q-Switch and also RF driver for your application.
