BBO（β-BBO) Crystals
The frequency multiplication coefficient of β-BBO crystal is large, and the frequency multiplication threshold power is 3-4 times higher than that of KDP crystal
It can achieve phase matching in a wide band (200–3000nm), with high laser damage threshold and stable properties of physical and chemical.
This crystal is a candidate for frequency doubling of short-pulse (1ns), high-power (1GW) lasers.
Advantage：
- High optical homogeneity
- High damage threshold
- Wide temperature-bandwidth of about 55℃
- Wide transmission region from 190nm to 3500nm
- Broad phase matchable range from 409.6nm to 3500nm
- Large effective second-harmonic-generation coefficient about 6 times greater than that of KDP crystal
