AI Technical Summary

Problems solved by technology

However, due to its relatively small birefringence (Δn=0.04-0.05), it cannot achieve phase matching in the deep ultraviolet region, and the shortest frequency doubling wavelength is 276nm
Similar to LBO crystals, CBO and CLBO crystals also limit their application in the deep ultraviolet region due to their relatively small birefringence
Although BBO crystal has a large frequency doubling coefficient and birefringence, due to its relatively high UV absorption cut-off edge (189nm), its shortest frequency doubling wavelength is 204.8nm, which limits its application in the deep ultraviolet region.
KBBF can achieve direct six-fold frequency output of 1064nm fundamental frequency light, but due to the layered growth habit of KBBF, it is difficult to grow large-sized crystals, which limits its application to a certain extent
