| 发明名称 | Method and apparatus for adjusting pulse parameters in a solid-state chirped-pulse amplifier system | ||
| 摘要 | Optical apparatus for amplifying pulses in a pulsed laser-beam includes a pulse-stretcher having a single transmission-grating in a multi-pass configuration at a non-normal incidence angle. A regenerative amplifier amplifies stretched pulses in the laser-beam. A pulse-compressor including two spaced-apart reflection-gratings in a multi-pass configuration compresses the amplified pulses. Pulse-parameters of the compressed amplified pulses are optimized by iteratively adjusting the incidence angle of the pulsed laser-beam on the transmission-grating of the pulse-stretcher and the spacing between the reflection-gratings of the pulse-compressor. | ||

| 主权项 | 1. In optical apparatus for amplifying a pulsed laser-beam, the apparatus including a pulse-stretcher having a single transmission-grating in a multi-pass configuration at a non-normal incidence angle for temporally stretching pulses in the laser-beam, an amplifier for amplifying the temporally stretched pulses in the laser-beam, and a pulse-compressor including at least one reflection-grating in a multi-pass path configuration, for compressing the amplified temporally-stretched pulses, a method of optimizing parameters of the compressed amplified pulses, comprising: iteratively adjusting only the incidence angle of the pulsed laser-beam on the transmission-grating of the pulse-stretcher, and the length of the multi-pass path in the pulse-compressor in order to adjust the group delay dispersion (GDD) and the third order dispersion (TOD) of the compressed amplified pulses. | ||
