Q-SWITCH

Industry standard for Nd:YAG lasers 1.Superior corrosion resistance 2.Stainless steel cooling channels

Q-SWITCH

1.A ‘Stallion’ version of our industry standard water cooled Acousto-optic Q-Switch, for use in high power lamp or diode pumped Nd:YAG lasers.

2.The patent pending ‘Stallion’ manufacturing technique provides superior corrosion resistance whilst maintaining optimum performance and RF power handling capabilities up to 100W.

3.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.

4.In addition to the standard product shown, custom configurations are available for specialized applications. These include alternative housing options, wavelengths and RF frequencies.
