Abstract
We report on a 40 kHz repetition rate travelling wave optical parametr ic amplifier (OPA) system designed for ultrafast spectroscopy, Two ind ependently tunable OPAs seeded from a single white light continuum sou rce each generate 40-75 nJ per pulse over a 480-730 nm spectral range when pumped by 1 mu J, 130 fs, 400 nm pulses derived from a Ti:sapphir e regenerative amplifier. After removal of chirp, the cross-correlatio n between the two OPAs was measured to be 150 fs, Bandwidth was 205 +/ - 85 cm(-1), consistent with the transform limit of the compressed pul ses. A single OPA gave up to 280 nJ per pulse signal energy when pumpe d with 3 mu J per pulse.
