S. Schiemann et al., FOURIER-TRANSFORM-LIMITED LASER-PULSES TUNABLE IN WAVELENGTH AND IN DURATION (400-2000 PS), IEEE journal of quantum electronics, 34(3), 1998, pp. 407-412
A combined system of an injection-seeded pulsed dye amplifier and a pu
lse compressor based on stimulated Brillouin scattering (SBS) is inves
tigated, It allows for the generation of powerful pulses both tunable
in wavelength and in duration. Online tuning of the pulse duration is
possible due to the dependence of SBS compression on input energy, A r
ange of 400-2000 ps at up to 100 mJ output energy is demonstrated. The
output pulses are temporally and spectrally resolved to investigate t
he properties of this system. Coherent nearly Fourier-transform-limite
d pulses of variable pulse duration in the extreme ultraviolet (UV) ar
e produced employing harmonic conversion. As an application of such pu
lses a single rotational line of H-2 at 98-nm wavelength ig excited, d
emonstrating that the system may be used for laser-spectroscopic studi
es to simultaneously gain spectral as well as dynamical information.
