Hangzhou Shalom Electro-optics Technology Co., Ltd. LBO 5x5x15mm for SHG@1064nm Type 1 20205-008

• Stocked and custom crystals available • Wide bandwidth for Type I and Type II non-critical phase-matching (NCPM) • Large effective SHG coefficient • High damage threshold: >10GW/cm^2 for 1064nm, TEM00, 10ns, 10HZ (with no coating) • Maximum size: 70x70x20mm • Thin LBO crystals (standard thickness 1-4mm) for femto-line laser are also available Lithium Tri-borate (LBO, or LiB3O5) Crystal is one of the most useful nonlinear optical materials, not only because of its relatively large conversion coefficient (which is 3 times the magnitude of that of KDP), but also its high damage threshold (which is the highest among the inorganic nonlinear crystals), wide angular bandwidth and small walk-off angle. LBO crystal has a broad optical transmission range from 160 to 2600nm, making them appropriate for high power military/medical Nd:YAG/Nd:YLF lasers, Ti: Saphhire and Cr:LiSAF lasers, etc. It excels in high power SHG with minimal thermal lensing effect compared to KTP. Hangzhou Shalom offers both stocked and custom LBO crystals for THG and SHG of Nd-doped lasers, Type I and Type II non-critical phase matching, and OPO/OPA. The crystals feature great optical homogeneity and very few stress stria. The damage thresholds are impressive, which gives an exceptionally high level of >10GW/cm^2 for 1064nm, TEM00, 10ns, 10HZ (with no coating). The surface quality could be leveraged to 10/13 Scratch/Dig.
