Abstract
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.

A method for controlling a burst mode of a pulse laser device including:
- a laser generator including at least one pulse laser source which outputs the optical pulse, a continuous laser source which outputs a continuous wave, a laser source driver which controls an operation time of the pulse laser source and the continuous laser source, and a light guide unit which guides the seed laser signals generated from the pulse laser source and the continuous laser source to the subsequent optical amplifier;
- and an optical amplifier which amplifies the seed laser signal,
- wherein the laser source driver of the laser generator controls peak outputs of each of the subsequent pulse signals by varying an operation time of the continuous laser source generation time of the standby signal in a quiet period in which the pulse signal is not generated to control a profile of a pulse train into an arbitrary waveform.
