An accurate positioner suitable for sequential agile tuning of pulse burst and CW lasers

摘要

A positioning system (51a) including a sensor (52), a drive sequencer (47a) and an actuator (56). The sensor (52) senses the actuator position and provides position signals to drive the sequencer (47a) which responsively computes and drives the actuator (56) in open loop moves containing dwell intervals of position. The actuator (56) positions a mirror (66) or other load means to reflect an optical beam as desired. Either preprogrammed or non-repeating sequencing of actuator (56) stopping positions can be synchronized with a laser. During dwell times, mirror position accuracy better than 10 microradians is suitable for tuning CO2 pulse burst or CW lasers.
