Passive Q-Switching of a Flashlamp-Pumped Ti:Sapphire Laser with a Stimulated Brillouin Scattering Nonlinear Mirror.

High-power passively Q-switched thulium fiber laser with distributed stimulated Brillouin scattering.

We report a novel passively Q-switched 2 μm Tm(3+) fiber laser simply by distributed stimulated Brillouin scattering with an all-fiber configuration. The maximum output power is 2.49 W with an optical-to-optical slope efficiency of 12%, and the laser wavelength is centered at ~1991 nm with a spectral width of >10 nm. The single pulse energy can be over 50 μJ with a pulse width of about 20 ns, a...

CHARACTERIZATION OF STIMULATED BRILLOUIN SCATTERING AND Bi-EDFA AS A CONVENTIONAL BRILLOUIN FIBER LASER

Stimulated Brillouin Scattering (SBS) is one of the nonlinear process that can occur in optical fiber if the input power at low level [1,2]. It is a natural scattering process associate to the propagation of light in a medium. Due to the interaction of light with the propagation medium, different scattering components are generated: Rayleigh, Brillouin and Raman component. The resulting scatter...

All solid-state diode pumped Nd:YAG MOPA with stimulated Brillouin phase conjugate mirror

At the Nederlands Centrum voor Laser Research (NCLR) a 1 kHz diode-pumped Nd:YAG Master Oscillator Power Amplifier (MOPA) chain with a Stimulated Brillouin Scattering (SBS) Phase Conjugate mirror is designed and operated. A small Brewster angle Nd:YAG slab (2 by 2 by 20 mm) is side pumped with 200 ,us diode pulses in a stable oscillator. The oscillator is Q-switched and injection seeded with a ...

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...
