We present the results of extensive Bloch equation numerical simulations, both for cw and for various pulsed laser formats and applications.

We report on a 39 W SBS-suppressed narrow-linewidth (

We report our works on fiber Raman amplifiers with linewidth of ~10MHz. Up to 1 W, < 12.5 MHz 1178 nm laser is obtained by Raman amplification of a distributed feedback diode laser seed in standard fibers, limited by stimulated Brillouin scattering. By introducing temperature non-uniformity along fiber, we are able to push back the threshold of stimulated Brillouin scattering and increase the output to 1.5 W. ©2008 Optical Society of America

We combine incoherent high-power laser beams using beam deflection on multiple simultaneous acoustic gratings in an anisotropic paratellurite (TeO2) crystal by reversing the usual direction of beam deflection. We discuss loss mechanisms and parameter optimization.

We investigate the potential of fiber Raman lasers in the visible wavelength region, which have hardly been explored yet, motivated by developing a fiber based 589nm source for laser guide star adaptive optics.

We did calculations structure function of phase fluctuations in signal from real star and set of spherical waves, formed in plane of LGS. We developed the approach on formation laser guide star free from focal anisoplanarity.

11W of 938nm light was produced in an Nd3+ fiber laser. Optimization of the ratio of the fiber core and cladding areas permitted operation of the laser at room temperature by minimizing 1088nm gain.
