Efficient UV output (205nm-310nm) with a SHG efficiency of over 10% at wavelength of ≥206nm was obtained in type I BBO, and 36% BBO crystals conversion efficiency  was achieved for a XeC1-laser pumped Dye laser with power 150KW which is about 4-6 times higher than that in ADP. The shortest SHG wavelength of 204.97 nm with […]

bbo crystal conversion efficiency This article discusses the second-harmonic generation (SHG) of tightly focused fs laser pulses in a BBO crystal. It was found theoretically and demonstrated experimentally that the spatial walk-off (SWO) and group-velocity dispersion (GVD) effects can suppress the pulse distortion and gain depression of SHG due to group-velocity mismatch (GVMM), thus keeping […]

In optical second-harmonic generation coherent optical radiation of frequency 2ω is generated, through the use of a medium with the appropriate nonlinear susceptibility, from incident coherent optical radiation of frequency ω. For the process to take place efficiently, the phase matching condition (colinear geometry) k(2ω)=2k(ω) k(2ω)=2k(ω) must be fulfilled, where k(ω)and k(2ω)are the wave numbers, […]
