摘要： An OPCPA apparatus of the present invention includes an optical pulse stretcher (100) for temporally stretching laser light, and applying short-wavelength preceding-type chirping. Pump lasers (210, 220) emit pump laser light. A first OPA unit (310) receives the pump laser light, and a signal having passed through the optical pulse stretcher, amplifies the signal, and generates a first idler. A first optical signal separation unit (410) separates output light of the first OPA unit into the first idler and remaining light (pump and signal). A second OPA unit (320) receives the first idler and another pump laser light, amplifies the first idler, and generates a second idler. A second optical signal separation unit (420) separates output light of the second optical parametric amplification unit into an amplified first idler and remaining light (pump and second idler). An optical pulse compressor (600) temporally compresses the amplified first idler.

摘要： The object of this invention is to provide a phase stabilization device for stimulated brillouin scattering-phase conjugate mirrors and a light amplification apparatus using the phase stabilization device. A light amplification apparatus of the present invention includes a polarizer (70) for polarizing light beams reflected from a plurality of stimulated brillouin scattering-phase conjugate mirrors and causing the light beams to interfere with each other. A detector (80) acquires an interfering beam resulting from interference of the polarizer (70), and outputs the interfering beam. A phase controller (90) controls phase using the interfering beam acquired by the detector. Therefore, the apparatus of the present invention can stably lock the phase for a long period of time, and can be used in various industries and for scientific research in cases where a high repetition rate and high power are required.

摘要： The present invention relates to an OPCPA apparatus. The OPCPA of the present invention includes an optical pulse stretcher (100) for outputting chirped laser light using odd-order dispersion (third-order dispersion is mainly used). A pump laser (200) outputs pump laser light. An OPA unit (300) 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 (400) separates output light of the OPA unit into the signal, the idler, and remaining light (pump). An optical pulse compressor (600) 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.
