Q Switch

We offer clients technically advanced range of Q Switch for use in high-power Nd:YAG laser systems.Powered from 220VAC or 110VAC, the modulation inputs allow either full digital control or activation of an internal pulse generator. First pulse suppression is automatically implemented.Our range of products are as follow.

Q Switch & RF Driver

We offer clients a wide range of Q Switch & RF Driver that come 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. Through an innovative design and manufacturing process, RF powers up to 100W may be applied.Standard options include a choice of frequencies (24 to 68MHz), active apertures (1 to 8mm), acoustic modes (compressional for linear polarisation, shear for unpolarised) and water connectors. Customized housings are available for OEM’s.

Accousto Optics Modulators

We offer a wide range of standard AO Modulators, for digital or analogue intensity modulation of laser beams. Their main specifications are as follows:

* Wavelength Range: 240nm to 2100nm
* Drive Frequencies: 20MHz to 350MHz
* Optical Rise-Times: Down to 5ns
* Modulation Bandwidths: Up to 100MHz
* Interaction Materials: Tellurium Dioxide, Lead Molybdate, Fused Silica, Crystal Quartz,halcogenide Glass, Flint Glass.

provides the electronic signal operating the AO Modulator. With a digital driver, an external TTL signal enables rapid on and off switching of the optical beam. Alternatively an anologue driver enables a variable intensity output, typically from 0% to 85% of the input beam. The maximum modulation bandwidth, or optical rise-time, is a function of the acoustic transit time across the optical beam. Therefore, for the highest speeds it is often necessary to focus the optical beam down to a small spot inside the modulator.
