Au Coating BBO for SHG Near IR Laser
Advantages of Beta-BBO Crystal
• Broad phase matching (SHG) range from 409.6nm to 3500nm
• Good mechanical and physical properties
BBO is an effective NLO crystal for the SHG, THG, or FHG of Nd:YAG lasers, and the first-rate NLO crystal for the FHG at 213nm. Conversion efficiencies of more than 70% for SHG, 60% for THG and 50% for 4HG, and 200mw output at 213 nm (5HG) have been obtained through using Wisoptic's BBO, respectively.
BBO is also an efficient crystal for the intracavity SHG of excessive energy Nd:YAG lasers. for the intracavity SHG of an acousto-optic Q-switched Nd:YAG laser, greater than 15 w average power at 532 nm generated via an AR-coated BBO crystal produced by Wisoptic. Whilst it's pumped by the 600 mW SHG output of a mode-locked Nd:YLF laser, 66 mW output at 263 nm was created from a Brewster-cut BBO in an external resonant cavity.
Beta-BBO's main applications
• 2nd, 1/3, fourth and 5th harmonic era of nd lasers
• frequency-doubling, -tripling and -mixing of dye lasers
• second, 0.33 and fourth harmonic era of ti:al o and alexandrite lasers
• optical parametric amplifiers (opa) and optical parametric oscillators (opo)
• frequency-doubling of argon ion, cu-vapor and ruby lasers
