Laser synthesis system and high-power laser experimental apparatus

Abstract

The invention provides a laser synthesis system and a high-power laser experimental apparatus. The laser synthesis system comprises a pulse seed source, a beam splitting module, a first amplifying module, a second amplifying module and a beam combining module, wherein the pulse seed source is used for emitting laser pulse and transmitting the laser pulse to the beam splitting module; the beam splitting module separates the laser pulse into first light wave and second light wave according to the polarization property, and transmits the first light wave and the second light wave to the first amplifying module and the second amplifying module correspondingly, wherein the polarization directions of the first light wave and the second light wave are perpendicular to each other; the first amplifying module is used for amplifying the first light wave and transmitting the amplified first light wave to the beam combining module; the second amplifying module is used for amplifying the second light wave and transmitting the amplified second light wave to the beam combining module; and the beam combining module performs synthesis on the first light wave and the second light wave to obtain thesynthesized laser. Through the mode of performing beam splitting and amplifying treatment firstly and then performing synthesis treatment, overlaying and amplifying of two paths of signals can be realized to obtain the high-power pulse laser through synthesis, with higher stability; and in addition, the damaged rate of related devices is greatly lowered.

[0003] The inventor found in the research that the pulsed laser device in the related art is limited by the limited energy storage capacity of the amplifier, so that multi-stage amplification is required in the case of generating high-power pulsed laser. However, the extremely high The high power density leads to a high damage rate of the device, and factors such as the high gain required by the multi-stage amplification cause the parasitic oscillation and other factors to make the generated high-power pulsed laser less stable.
