Pulse laser system with high peak power and system comprising multiple optical enhancement resonators

Abstract

A high peak power pulsed laser system configured to output a high peak power pulsed laser with a peak power of more than 0.1 GW and a frequency of 0.1 Hz to 10 Hz, the system comprising: a source laser generating a continuous wave (CW) or pulsed laser, in particular a pulsed laser of more than 10 MHz; a coherent beam combination laser coupled to the laser source and configured to amplify the CW or pulsed laser generated by the source laser from a first energy level N to a second energy level O; a short optical enhancement resonator (SOEC) coupled to the coherent beam combination laser and configured to further excite the second energy level of the CW or pulsed laser from the second energy level O to a third energy level P;a first extraction device coupled to the SOEC and configured to extract the CW or pulsed laser and generate a power-enhanced laser pulse; a long optical enhancement resonator, LOEC, which further excites the power-enhanced pulse from an energy level P to an energy level Q; a second extraction device coupled to the LOEC and configured to extract a higher-energy laser pulse with a peak power of more than 0.1 GW and a frequency of 0.1 Hz to 10 Hz into a region outside the LOEC.
