he presentation of LBO Crystal

Lithium Triborate LiB305or LBO is a newly developed nonlinear optical crystal.It is unique in many aspects,especially its wide transprency range,moderately high nonlinear coupling,high damage threshold and good chemical and mechanical properties.Its transmission range is from 0.21>mto 2.3 >m.Type I SHG ,and also provides room temperature NCPM fro Type II SHG at 0.8-1.1>m.iIt possesses a relatively large angular acceptance bandwidth,reducing the beam quality requirements for source lasers.

LBO Crystal Features :
1 Broad transparency range from 160nm to 2600nm (SHG range from 550nm to 2600nm).

2 Type I and type II non-critical phase-matching (NCPM) over a wide wavelength range.

3 Relatively large effective SHG coefficient (about three times larger than that of KDP)

. 4 High damage threshold (18.9 GW/cm2 for a 1.3ns laser at 1054nm).

LBO Crystal Applications:

1 High power Nd:YAG and Nd:YLF lasers for R&D and military applications.

2 Ti:Sapphire, Alexandrite and Cr:LiSAF lasers. 3 Medical and industrial Nd:YAG lasers.

4 Diode laser pumped Nd:YVO4, Nd:YAG and Nd:YLF lasers. 5 Frequency-tripling (THG) of Nd:YAG and Nd:YLF lasers.
