High Temperature form BBO ( a -BaB 2 O 4 ) is a negative uniaxial crystal. It has large birefringence over the broad transparent range from 189 nm to 3500 nm. The physical, chemical, thermal and optical properties of a-BBO crystal are similar to those of b-BBO. However, the nonlinear optical properties of a-BBO crystal […]
Nonlinear Crystals The Nonlinear Optical (NLO) Crystals are used in frequency conversion for lasers. We have a complete line of NLO crystals including DKDP/KDP, BBO, LBO, KTP, KTA, and LiNbO3 crystals, etc. The basic properties, advantages and applications of these crystals are described in this URL. https://www.astarphotonics.com/product-showcase/nlo-crystals/ NLO Crystals (Non-linear Optical Crystals) are used for […]
I have been reading about entangled particles, lasers, the two slit experiment, etc. I really know nothing from physics (i.e. equations, formulas, theory); so please respond accordingly. From my understanding, one typically uses a beta barium borate crystal (BBO) to entangle particles. 1) How does this work? Does one simple purchase a laser pointer and […]

bbo crystal damage threshold high damage threshold of 10 GW/cm for 100 ps pulse-width at 1064 nm A-Star bbo crystal damage threshold BaB2O4 is a nonlinear optical crystal which combines a number of unique features. These features include wide transparency and phase matching ranges, large nonlinear coefficient, high damage threshold and excellent optical homogeneity. Therefore, BBO […]
BBO Crystals Supplier A-Star BBO crystal remains the most versatile nonlinear optical crystals thanks to its unique combination of optical properties (e.g. broad transmission and phase matching ranges, high damage threshold) and availability of large, high quality single crystals. A-Star’s BBO crystals have been widely used in second, third, fourth or fifth harmonic generations for high […]
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 […]
Second-harmonic generation from regeneratively amplified femtosecond laser pulses in BBO and LBO crystals bbo crystal second harmonic generation The spectral and temporal characteristics and optical-conversion efficiency of ∼150−fs∼150-fs laser pulses at 400 nm generated by second-harmonic generation (SHG) of a regeneratively amplified mode-locked Ti:sapphire laser were investigated both theoretically and experimentally. The theoretical investigation was […]
