Compact high energy mid wave OPCPA laser

摘要

Systems and methods of optical parametric chirped pulse amplification for laser pulses are provided. Techniques and components include replacing pulse stretcher and/or pulse compressors with chirped volume Bragg gratings (CVBGs) to reduce size, weight, cost, and environmental sensitivity of the laser system.

主权项

1. A chirped pulse amplification (CPA) laser system, the system comprising:
a seed laser; a pump laser; an amplifier having an input side and an output side, where the seed laser and the pump laser are disposed on the input side of the amplifier, the amplifier being configured to generate a signal output pulse and an idler output pulse; a chirped volume Bragg grating (CVBG) pulse stretcher disposed between the seed laser and the input side of the amplifier; a grating compressor disposed on the output side of the amplifier; an idler extraction module disposed on the output side of the amplifier between the amplifier and the grating compressor; and an idler grating compressor disposed on the output side of the amplifier such that the idler grating compressor receives an idler pulse extracted by the idler extraction module.
