non-linear opticallaser

BBO 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 The main application of BBO crystals: • Second, third, fourth and fifth harmonic generation of Nd:YAG • Frequency-doubling, -tripling and -mixing of dye lasers • Optical parametric amplifiers (OPA) and optical parametric oscillators (OPO) • Second, third, fourth and fifth harmonic generation of Ti: sapphire and alexandrite • Frequency-doubling of Argon ions, Cu vapor and ruby lasers • External intra-cavity SHG
