|Customization of electro-optics modulators|
The Equalaser is a device based on a feedforward loop. The parameter to stabilize (energy, power…) is measured on a sampled part of the beam. It is feed to photoconductors that drive directly a high voltage generator. The high voltage level, driven by the laser parameter to stabilize, is used in an electro-optic modulator to modify the main beam parameter.
Energy stabilization of pulses has been demonstrated this way (see figures) on the pulse itself by opposition to feedback loop.
Very specific know-how on photoconductors, high-voltage and fast electronics are combined with electro-optic technology in this device.
Being a true feedforward stabilization device, the Equalaser comes with the following characteristics :
The Equalaser is a technology transfer from Fastlite's Stabbler product.
