In the nonlinear optical crystal, BBO crystal is a kind of crystal with obvious comprehensive advantages and good performance. It has a very wide light transmission range, a large matching angle, a high resistance to light damage threshold, and a broadband temperature matching. Excellent optical uniformity, especially for the triple frequency of Nd:YAG lasers.

ADVANTAGES

-   Wide transparency

-   Broad phase-matching range

-   Small walk-off angle

-   High damage threshold

-   Wide acceptance angle
