The main properties of BBO
crystals：
BBO is a negative uniaxial crystal, and its o-ray
refractive coefficient (no) is higher than that of the e-ray (ne)
which can be calculated by Selleimer equation (λ in
μm):
no2 = 2.***9 *0.****8 /
(λ**0.****2) *0.****4 λ2
ne2 = 2.***3 *0.****4 / (λ**0.****7) *0.****6 λ2
BBO crystal in the Nd:YAG lasers:
BBO is 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 **3nm. Conversion efficiency more than *0%
for SHG, *0% for THG, *0% for 4HG, and **0mw output at **3nm have
been obtained, respectively. Besides, BBO is also an efficient
crystal for the intra- cavity SHG of high power Nd:YAG
lasers.
