BBO

BBO (beta-BaB2O4 ) crystal is an important nonlinear optical crystals with combination of unique optical properties.

Broad transmission and phase matching ranges, large nonlinear coefficient, high damage threshold and excellent optical homogeneity provide attractive possibilities for various nonlinear optical applications.

Advantages

Broad phase matching (SHG) range from 409.6nm to 3500nm

Wide transmission region from 190nm to 3500nm

Large effective SHG coefficient

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


Applications

SHG, THG, 4HG, 5HG of Nd lasers

SHG, THG, 4HG of Ti:Al2O3 and Alexandrite lasers


SHG, THG and Frequency-mixing of Dye lasers


SHG of Argon ion, Cu-vapor and Ruby lasers
OPA and OPO

Notes

BBO has a low susceptibility to the moisture. The user is advised to provide dry conditions for both the use and preservation of BBO.

BBO is relatively soft and therefore requires precautions to protect its polished surfaces.

When angle adjusting is necessary, please keep in mind that the acceptance angle of BBO is small.
