Beta-Barium Borate,β-BaB2O4,BBO
The main advantages of BBO:
• Broad phase matching second-harmonic-generation (SHG) range from 409.6nm to 3500nm
• Wide transmission region from 190nm to 3500nm
• Large effective SHG coefficient
• High damage threshold of 10 GW/cm2 for 100 ps pulse-widths at 1064nm
• High optical homogeneity with Dn 10-6/cm2
• Wide temperature bandwidth of about 55° (for type I SHG 1064nm)
• Good mechanical and physical properties
