PRODUCT DESCRIPTION

Laser Stabilization System (ST-LASS-II) is designed as an electro-optic feedback loop capable of reducing the amplitude variations commonly associated with lasers. The ST-LASS-II system enhances the signal to noise ratio of the laser over a broad bandwidth. Both an internal and external reference input is provided, allowing analog programming of the laser throughput.

The ST-LASS-II is particularly convenient for use in recording systems where laser power must be varied as a function of position on the recording medium (i.e. video disc, flat bed recorders, etc.). The system is composed of feedback electronics, power supply and electro-optic modulator with integrated beam-splitter and photodiode amplifier.
