Demonstration of laser pulse amplification by stimulated Brillouin scattering
The energy transfer by stimulated Brillouin backscatter from a long pump pulse (15 ps) to a short seed pulse (1 ps) has been investigated in a proof-of-principle demonstration experiment. The two pulses were both amplified in different beamlines of a Nd:glass laser system, had a central wavelength of 1054 nm and a spectral bandwidth of 2 nm, and crossed each other in an underdense plasma in a c...
متن کاملPulse Compression of Nd:YAG Laser with Stimulated Brillouin Scattering for Compton Backscattered X-Ray Source
Abstract. Compton backscattered x-ray source is developed in the energy region of a few hundred keV at Kansai Photon Science Institute of Japan Atomic Energy Agency (KPSI-JAEA). A remarkable feature of the Compton backscattered x-ray source is that the generated x-ray beam is a well-collimated and has a definite polarization property. The Compton backscattered x-ray source at KPSI-JAEA consists...
متن کاملNumerical Treatment of short Laser Pulse Compression in transient stimulated Brillouin Scattering
Received: 10.04.2002 Accepted: 24.04.2002 Abstract Results of numerical investigation of the compression process of short pulses during essentially nonstationary SBS are presented, taking into account the diffraction and focusing of the interacting light beams and the finite oscillation period and lifetime of hypersound waves in nonlinear media.
متن کاملForward and backward stimulated Brillouin scattering of crossed laser beams.
The simultaneous forward and backward stimulated Brillouin scattering (SBS) of crossed laser beams is studied in detail. Analytical solutions are obtained for the linearized equations governing the transient phase of the instability and the nonlinear equations governing the steady state. These solutions show that backward SBS dominates the initial evolution of the instability, whereas forward S...
متن کاملAmplification of an ultrashort pulse laser by stimulated Raman scattering of a 1 ns pulse in a low density plasma
Experiments are described in which a 1 mJ, 1 ps, 1200 nm seed laser beam is amplified by the interaction with an intersecting 350 J, 1 ns, 1054 nm pump beam in a low density 1 1019 /cm3 plasma. The transmission of the seed beam is observed to be enhanced by 25 when the plasma is near the resonant density for stimulated Raman scattering, compared to measured transmissions at wavelengths just bel...
