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.

主权项

1. A pulse laser device, comprising:
a laser generator configured to generate pulse signals, a standby signal, and a seed laser signal which includes the pulse signals and the standby signal; and an optical amplifier configured to amplify the seed laser signal, wherein the laser generator is configured to generate the standby signal to consume energy of the optical amplifier in a time period between the pulse signals, wherein when the pulse laser device is operated in a burst mode, the standby signal is generated during a time period exceeding a reference time period, and wherein when the pulse laser device is operated in a variable burst mode, an intensity of the amplified signal may be controlled by the generation time of the standby signal.
