Outline of Final Research Achievements

Optically synchronized pump source is developed for stable optical parametric chirped-pulse amplification by reducing timing jitters between signal and pump pulses. Seed pulses for pump pulses are generated from a part of signal pulses. The wavelength of the seed pulses is stabilized by original feedback control system. The seed pulses are stretched by a fiber Bragg grating, and amplified by laser-diode pumped fiber amplifiers and bulk amplifiers. By the second harmonics generation, optically synchronized pump pulses are obtained for the optical parametric chirped-pulse amplification.
