We have constructed a low-cost, phosphate glass actively mode-locked, actively Q-switched oscillator that produces pulses from 150 to 1000 ps with high energy. This was accomplished by reducing the time required for relaxation oscillations to die out through the use of an acoustooptic feedback system. We describe system performance and construction details of this oscillator.
