IntraAction QE Series Acousto-Optic Q-Switch Driver
The QE Series of acousto-optic Q-switch drivers contain a crystal controlled RF oscillator, fast modulation circuit, free running pulse generator circuit with trigger capability, and a broadband RF power amplifier in a housing with power supply, RFI line filter, line switch, and fault/interlock circuit.
When the input gate voltage is < 0.8 volts, the RF output is continuously on for CW operation. For gated operation with the input gate voltage > 2 volts, the internal pulse generator controls the RF off pulse repetition rate (PRR) which is set via a front panel control. When the input trigger PRR is faster than the PRR setting on the front panel, the RF off PRR is externally controlled for triggered operation.
For gated or triggered operation, the pulse width is determined by the front panel setting. A monitor output, which is the inverse of the RF output envelope, is provided. The fault/interlock circuit which can be connected to the thermostat of a Q-switch will latch the power supply off when an open condition is present. High VSWR, overpower, and low power indicator options are available.
