Profile: Fastpulse Technology, Inc. designs & manufactures electro-optic light modulators, Q-switches, laser pulse pickers, choppers and extraction systems. The 8025RS variable width high voltage pulse generator provides adjustable width and high voltage pulses with fast, symmetrical rise & fall times. It uses a low jitter, differential high voltage MOSFET switching amplifier, which is triggered from an external event or synchronizing signal. The model GA-21R wide band amplifier is designed to operate with transverse field modulators. It uses two class A output amplifiers driven differentially from a common, single ended input.
