Abstract

We report on a traveling wave optical parametric generator producing tunable femtosecond pulses between 550 and 590 nm (signal) and between 1230 and 1450 nm (idler). The second harmonic of a 1 kHz repetition rate Ti:sapphire laser/regenerative amplifier system serves as an UV pump source. To achieve nearly bandwidth limited parametric pulses we combine a narrow band seeder with a broad band parametric amplifier. Pulse compression at the idler wavelengths is observed which is attributed to temporal gain narrowing. The optimization of simple seeder-amplifier configurations in the small signal limit at pump wavelength near 400 nm is analyzed with respect to achievable spectral narrowing and pulse shortening in the amplification process.
