Spectral phase retrieval of 8 fs optical pulses at 600 nm by using a collinear autocorrelator with 300-(mu)m-thick lithium triborate crystals

摘要

We report on noniterative spectral phase retrieval of 1.1 nJ, 8fs pulses at 600nm by using 300-(mu)m-thick lithium triborate crystals in a standard collinear autocorrelator with approx=2 min data acquisition time. This method is simple, sensitive, and immune to the spectral distortion and UV absorption of the linear and nonlinear optics.
