摘要：

The output pulses of a noncollinearly phase-matched optical parametric amplifier (NOPA) are fully characterized by spectral phase interferometry for direct electric-field reconstruction (SPIDER). The SPIDER setup has been optimized for online diagnosis of tunable visible pulses with a I kHz repetition rate and 10-40 fs duration. The compression of the NOPA pulses by different prism sequences and commercially available chirped mirrors is investigated. For flexible phase control the end mirror of a fused-silica prism compressor has been replaced by a deformable mirror. With an evolutionary strategy guided by the spectral phase information of the SPIDER, optimal compression of the NOPA pulses to a 7.6 fs duration is achieved.
