Nonlinear polarization interferometer: application for efficient cross polarized wave generation and beam shaping
Novel (3)-based nonlinear polarization interferometer is proposed. It allows cross polarized wave generation with enhanced efficiency and obtaining different beam shapes of the generated cross-polariz...
Dynamics of femtosecond laser pulses in air and in vacuum
We applied the method of the amplitude envelopes to investigate fsec optical pulses in air and in vacuum and and obtain new linear amplitude equations governing their propagation. The obtained amplitu...

Weconsider the femtosecond phase-matched noncollinear second-harmonic generation (SHG) in StrontiumBarium Niobate (SBN) crystals with random ferroelectnc domains. We studyboth planar and radial second-harmonic (SH) radiation for the averageinput power Pf up to 600 mW. We show thatthe effect of thermal self-focusing of the fundamental wave occurringat Pf > 250 mW results in novel effects includingthe spatial localization of SHG, a change of the SHefficiency slope, and significant spectral broadening of both fundamental andSH beams
