PULSE LASER OSCILLATOR AND PULSE LASER OSCILLATION CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a pulse laser oscillator capable of changing voltages applied to a plurality of electro-optical devices over time, respectively, extending a pulse width of a laser beam, and reducing a peak energy of a pulse laser outputted.;SOLUTION: The pulse laser oscillator comprises: a plurality of electro-optical devices 6a and 6b which polarize light according to applied voltages; and a voltage controller 7 which applies voltages to the plurality of electro-optical devices 6a and 6b, respectively, and controls the voltages. The voltage controller 7 changes voltages applied to the plurality of electro-optical devices 6a and 6b over time, respectively, and controls a pulse width of a laser beam.;COPYRIGHT: (C)2013,JPO&INPIT
