PULSE LASER DEVICE AND BURST MODE USING SAME, AND METHOD FOR CONTROLLING A VARIABLE BURST MODE

摘要

The present invention relates to a pulse laser device, and more particularly, to a pulse laser device which can be operated in a burst mode, in which the output of a low-output laser generator is adjusted so as to enable the uniform control of the profile of the peak output of a final output optical pulse train, and in a variable burst mode, in which the profile of the final output optical pulse train can be controlled into an arbitrary waveform. The pulse laser device according to the present invention comprises: a laser generator generating a pulse signal and a seed laser signal including a standby signal variably outputted in a quiet period of said pulse signal; an optical amplifier amplifying said seed laser signal so as to generate an amplified signal; a nonlinear wavelength converter nonlinearly outputting a wavelength conversion signal according to the intensity of said amplified signal; and an optical separator separating an output pulse from said wavelength conversion signal.
