he BBO Crystal is a high-temperature phase of BaB2O4, is anexcellent birefringent crystal an efficient NLO crystal for thesecond, third and fourth harmonic generation of Nd: YAG lasers,and the best NLO crystal for the fifth harmonic generation at 213nm. Conversion efficiencies of more than 70% for SHG, 60% for THGand 50% for 4HG, and 200 mW output at 213 nm (5HG) have beenobtained, respectively. BBOCrystals havebeen widely used in 2,3,4 or 5 harmonic generations for highpower visible/UV sources, and optical parametric conversions forhigh power broadly tunable sources.
