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 […]
A-star bbo crystal type 1 bbo crystal Type 1 and bbo crystal Type 2 phase matching are used in OPO devices based on BBO crystals and designed for pump at different harmonics (up to fifth) of Nd:YAG lasers. bbo crystal Type 1 of interaction gives a larger tuning range and higher parametric amplification rate comparing […]
