we offers high grade Czochralski (CZ) grown BB0 crystals with good homogeneity, low defects and low absorption.
BBO Crystals Feature:
●Broad phase-matchable second-harmonic-generation (SHG) range from 409.6nm to 3500nm
● Wide transmission region from 190nm to 3500nm
●Large effective SHG cofficient
●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
BBO Crystals Have Been Applied to:
●Second, third, fourth and fifth harmonic generation of Nd: lasers
●Frequency-doubling, -tripling and -mixing of dye lasers
●Optical parametric amplifiers (OPA) and optical parametric oscillators (OPO)
●Frequency-doubling and -tripling of ultrashort pulse Ti: sapphire and dye lasers
●Frequency-doubling of Argon ions, Cu vapor and ruby lasers
●External intra-cavity SHG
