The bbo crystals are a high-temperature phase of BaB2O4, is an excellent birefringent crystal an efficient NLO crystal for the second, third and fourth harmonic generation of Nd: YAG lasers, and the best NLO crystal for the fifth harmonic generation at 213 nm. Conversion efficiencies of more than 70% for SHG, 60% for THG and 50% for 4HG, and 200 mW output at 213 nm (5HG) have been obtained, respectively.
