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 […]
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, […]
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 […]
BBO Crystal Second Harmonic Generation Second-harmonic generation Second harmonic generation (also called frequency doubling or abbreviated SHG) is a nonlinear optical process, in which photons with the same frequency interacting with a nonlinear material are effectively “combined” to generate new photons with twice the energy, and therefore twice the frequency and half the wavelength of […]
