Beschreibung
Zusammenfassung:	An optical parameter chirped pulse amplifying device comprises a chirped pulse mode-locked laser, an optical splitter, a low-temperature ytterbium-doped yttrium aluminium garnet (Yb: YAG) regenerative amplifier, a frequency doubling crystal, a stretcher, a nonlinear crystal and a compressor. The isogenous optical parameter chirped pulse amplifying (OPCPA) device is realized by means of excellent thermal management performance of Yb: YAG crystals and the gain narrowing effect of the regenerative amplifier. The device provided by the invention is simple and compact and high in signal-to-noise ratio; the repetition frequency of the device can be increased to several thousand hertz kHz; and the device can be applicable for picosecond (ps) level of cascading OPCPA.
