Аннотация:We demonstrate generation of broadband high-intensity picosecond pulses using a non-collinear
optical parametric amplifier, seeded with a broadband cavity-less dye laser and pumped using
the second-harmonic of a picosecond Nd:YAG laser. With appropriate choice of the pump-seed
non-collinearity angle, we observed energy conversion from the pump to the signal wave of
around 15%, with the bandwidth of the amplified radiation around 445 cm–1 (20.7 nm) centered
around 680 nm. Energy of 1.2 mJ per pulse of duration around 26 ps has been achieved. A light
source with such parameters could be suitable for use in time-resolved broadband picosecond
CARS.
