“…In early studies, a limit was derived (see [3], [17]); later, estimates such as (see [10]) or the relation (see [26], [11]) were preferred. Our numerical model is not suited to predict ultimate limits because the second-order timederivatives were omitted [3].…”

Abstract-A pulse compressor based on stimulated Brillouin scattering (SBS) in liquids is experimentally and theoretically investigated. It allows for the compression of Fourier-transform limited nanosecond pulses of several hundreds of millijoules of energy with both high conversion efficiency and a high temporal compression factor. The two-cell generator-amplifier arrangement is of a compact design not requiring external attenuation of the generator cell input energy. Pulses from an injectionseeded, frequency-doubled Nd:YAG laser of 300-mJ energy were compressed by a factor variable between 6 and 21 at up to 75% reflectivity. Deviation from unity SBS reflectivity is predominantly determined by optical component losses. The generation of 270-ps pulses with high beam quality was achieved in liquid methanol. These powerful pulses of variable duration are difficult to produce with common laser systems and are highly suited for the generation of high-harmonics in gases.

“…The single-cell 0018-9197/97$10.00 © 1997 IEEE generator [ Fig. 1(a)] is not suitable to efficiently compress high-energy pulses because it provides high conversion efficiency only at low input energy [9], [10] , [7]. At high input energy, a poor efficiency [4] or only a weak compression was achieved [3].…”

“…However, they focused on the influence of structural parameters (cell length and focal length) on the efficiency of SBS pulse compression instead of medium parameters. Actually, the medium parameters have great influences on SBS pulse compression properties (Park et al, 2006;Hasi et al, 2008;Dong et al, 2012;Yoshida et al, 1997), especially phonon lifetime is the main factor affecting SBS pulse compression limit Gorbunov et al, 1983;Damzen et al, 1983a;1983b;Fedosejevs & Offenberger 1985;Schiemann et al, 1997). Therefore exploring the mediums with excellent SBS property and relatively short phonon lifetime is the first condition for hundreds picoseconds pulse compression SBS system.…”

Research on the compression properties of FC-3283 and FC-770 for generating pulse of hundreds picoseconds

This paper gives out two kinds of novel well-behaved stimulated Brillouin scattering (SBS) mediums, FC-3283 and FC-770. Numerical calculation and experimental measurements show these two mediums both having lower absorption, higher optical loads and short phonon lifetime, which making them good candidate mediums for highenergy high-power SBS. Using them as the mediums in the compacted two-cell SBS phase-conjugation mirror, it is easily to generate ultrashort phased-conjugated Stokes pulses just with hundreds picoseconds. When the incident light energy is beyond 200 mJ, the pulse width of 8 ns can be compressed to 200 ps or less in both mediums. Especially, the FC-770 is very suitable to be chosen for generating the SBS picosecond pulses with the narrowest compression pulse width of 109 ps and the highest energy reflectivity of 80%.

Abstract-A combined system of an injection-seeded pulsed dye amplifier and a pulse compressor based on stimulated Brillouin scattering (SBS) is investigated. 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 range of 400-2000 ps at up to 100 mJ output energy is demonstrated. The output pulses are temporally and spectrally resolved to investigate the properties of this system. Coherent nearly Fourier-transform-limited pulses of variable pulse duration in the extreme ultraviolet (UV) are produced employing harmonic conversion. As an application of such pulses a single rotational line of H2 at 98-nm wavelength is excited, demonstrating that the system may be used for laserspectroscopic studies to simultaneously gain spectral as well as dynamical information.Index Terms-Brillouin scattering, dye lasers, optical pulse compression, optical pulses, pulse compression methods, pulsed lasers.
