Beam Walk-On Effects On The Efficiency Of Frequency Conversion

Abstract

The authors previously reported a cylindrical focusing technique for the improvement of frequency doubling in beta barium borate (BBO) crystal, which has a rather narrow angular acceptance width and large walk-off effects. They discuss here a rigorous model, that includes the effects of beam spot sizes, spatial overlap, and beam walkoff for both types I and II polarization configurations. This theory has been developed for three-wave mixing such as sum frequency mixing and optical parametric oscillation. The efficiency for the phase-matched case of second harmonic generation (SHG). Results showing that the conversion efficiency is a strong decreasing function of the gain reduction parameter are given. The calculated SHG efficiency in types I and II barium borate crystal with walk-off effects is also shown.
