Abstract

The invention relates to a laser pulse control system and a laser pulse control method. The laser pulse control system provides a first polarization pulse through a seed source. An isolation module converts the first polarization pulse into a second polarization pulse which can enter a regenerative amplifier through isolation processing, so that the regenerative amplifier performs polarization conversion and amplification in different modes on the pulse, single pulses or pulse strings with different pulse numbers and energy are obtained and output to the outside through the isolation module, so that flexible switching between different modes is achieved through a simple structure according to actual needs, use is convenient for users, and the laser processing requirement is better met.

Description

technical field [0001] The invention relates to the field of laser control, in particular to a laser pulse control system and a laser pulse control method. Background technique [0002] Ultrafast laser is the key technology in many fields such as laser processing. The damage caused by heat accumulation to the surrounding materials of the target position during laser processing, as well as the more significant nonlinear effect of materials caused by high laser intensity, make the processing quality and efficiency significantly and decrease. [0003] In order to improve the above situation, there are many exemplary ways, for example, by selecting a burst-mode ultrafast laser to process transparent materials, reducing the laser filamentation threshold, and lengthening the focal depth range of the beam, thereby reducing the accumulation of excess heat around the target processing position and improving Processing efficiency; for example, a burst pulse is obtained based on exter...
