Abstract
The present invention relates to an OPCPA apparatus. The OPCPA of the present invention includes an optical pulse stretcher () for outputting chirped laser light using odd-order dispersion (third-order dispersion is mainly used). A pump laser () outputs pump laser light. An OPA unit () receives the pump laser light and the chirped laser light (signal), amplifies the signal using the pump laser light, and generates an idler. An optical signal separation unit () separates output light of the OPA unit into the signal, the idler, and remaining light (pump). An optical pulse compressor () compensates for pulse chirping caused by odd-order dispersion that is imparted by the optical pulse stretcher, thus temporally compressing the signal and the idler, which overlap each other.
