Main Features:
• Broad transparency range from 160nm in UV to 2600nm in IR;
• Relatively large effective SHG coefficient (about three times that of KDP);
• High effective non-linear coefficient ,wide acceptance angle and small walk-off;
• High damage threshold (>10GW/cm2 for 1064nm, 20ns, 50Hz);
• Type I and type II non-critical phase matching (NCPM) in a wide wavelength range;
• High optical homogeneity (dn~10-6/cm) and being free of inclusion;
• Spectral NCPM near 1300nm;
• Absorption: <30ppm/cm @1064nm <50ppm/cm for high power laser application.</div>
Typical 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;
• The VUV output at 187.7 nm is obtained by sum-frequency generation;
• 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;
• 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.
