VHE Acousto-Optic Q-Switch
The VHE (Very High Efficiency) acousto-optic Q-Switch is ideal for use in high gain, high power,linearly polarised Nd:YAG & NdYVO 4 lasers.Using a unique patented acousto-optic design, it provides up to 96% single pass loss modulation,compared to ~85% for conventional designs.
Utilising our ‘Stallion’ manufacturing technique providing superior corrosion resistance whilst maintaining optimum performance and RF power handling capabilities up to 100W.
In addition to the standard product shown, custom configurations are available for specialised applications. These include alternative housing options and custom wavelengths.
Our engineers are available to assist in selecting the most appropriate model of Q-Switch and also RF driver for your application.
