Description:

   Lithium Triborate (LiB₃O₅ or LBO) is an attractive nonlinear optical crystal.

Features:

• Broad transparency range from 160nm in UV to 2600nm in IR; 

• High optical homogeneity (dn~10-6/cm) and being free of inclusion; 

• Relatively large effective SHG coefficient (about three times that of KDP); 

• High damage threshold (>10GW/cm2 for 1064nm, 20ns, 50Hz); 

• High effective non-linear coefficient ,wide acceptance angle and small walk-off; 

• Type I and type II non-critical phase matching (NCPM) in a wide wavelength range; 

• Spectral NCPM near 1300nm;

• Absorption: <30ppm/cm @1064nm <50ppm/cm for high power laser application.

Applications:

• SHG and THG for middle and high power Nd: lasers at 1064nm for medical, industrial and military applications; 

• SHG for Ti:Sapphire, Alexandrite and Cr:LiSAF lasers; 

• SHG and THG of high power Nd: lasers at 1342nm & 1319nm for red and blue laser; 

• SHG for the Nd: Lasers at 914nm & 946nm for blue laser; 

• The VUV output at 187.7 nm is obtained by sum-frequency generation; 

• NCPM SHG over a broad wavelength range from 900nm-1700nm was measured;

• Phase matching process: SHG-554 nm fundamental, THG-794 nm, SFM-down to 160 nm; 

• Optical Parametric Amplifiers (OPA) and Oscillators (OPO) application.
