Abstract

We report measurement of efficient amplification of weak femtosecond supercontinuum seed pulses by use of a noncollinear optical parametric process in BBO crystal pumped with 150-fs pulses from a frequency-doubled regenerative-amplified Ti:sapphire laser at 390 nm. The highest amplification factor, 108, was achieved for 3×10-16 J energy seed pulses at wavelength of 560 nm
