METHOD OF FLEXIBLE BURST MODE OPERATION OF PULSE LASER SYSTEM WITH MULTIPLE SEED AND LASER SYSTEM WITH FLEXIBLE BURST MODE OPERATION

摘要

PURPOSE: A pulse laser apparatus using multiple laser sources and a control method for a burst mode and a flexible burst mode using the same are provided to change an output pulse, a repetition rate, and a pulse length by controlling the output of a laser generator. CONSTITUTION: A laser generator(110) comprises a pulse laser source(112) which outputs an optical pulse, a continuous laser source(114) which outputs continuous light, and a laser source driver(116) which controls operation time of the pulse laser source and the continuous laser source. The laser generator includes a light leading unit(118) which leads a seed laser signal generated in the pulse laser source and the continuous laser source to a following optical amplifier(120). The optical amplifier amplifies the seed laser signal. The laser source driver controls energy which is accumulated in the optical amplifier in continuous light by interconnecting the pulse laser source and the continuous laser source.
