| 摘要 |
The invention relates to a laser source capable of emitting energy pulses greater than or equal to 100 terawatts, consisting of a laser system including the following cascaded elements: a solid-state laser oscillator (1); a first amplification stage (2) with frequency drift; and a final amplification stage (6) with frequency drift; and a first filter having one or two nonlinear crystals and a third-order nonlinear optical susceptibility, capable of generating a crossed-polarization wave, referred to as a nonlinear crossed-polarization filter (3), and inserted between said two amplification stages (2, 6). The laser system further includes, between the first (2) and the final (6) amplification phases, at least one other nonlinear crossed-polarization filter (5), or N filters in the system where N>=2, and N-1 dispersion compensator(s) (4) placed at the output of the first filter(s) (3), respectively.
