Large Nonlinear Coefficient Beta Barium Borate BBO Nonlinear Optical Crystal
BBO Crystal Introduction:
Among the nonlinear optical crystals, BBO crystal is a crystal with obvious comprehensive advantages and good performance. It has a very wide light transmission range, a very low absorption coefficient, and a weaker piezoelectric ringing effect.
Compared with other electro-optic crystals BBO crystal has a higher extinction ratio, a larger phase matching angle, a higher anti-light damage threshold, a broadband temperature matching, and excellent optical uniformity, which is beneficial to improve the stability of laser output power, especially for Nd: YAG laser has a wide range of applications.
BBO Crystal Features :
- High damage threshold
- Large nonlinear optical coefficients
- Wide transparency ranges
- Wide phase matching ranges
