PURPOSE:To provide a laser oscillator, generating a pulse using an acousto- optical element used in the field of high precision processing, which ensures a variety of application in the field requiring the processing with less effect of heat by obtaining the pulse having shorter duration. CONSTITUTION:A first acousto-optical element 1 and a second acousto-optical element 2 are provided and modulation timings of respective RF signal inputs are deviated by about 100 ns. Thereby, the skirt of laser output pulse can be cut to make short the pulse duration. |
