BBO – Electro-optic Crystal – Customized Products
BBO electro-optic crystal, also known as barium metaborate crystal with the chemical formula BaB2O4. It is an electro-optical and nonlinear crystal with excellent overall performance.
Note:
$100 is a deposit, not the final price of the product. Please contact us for price if needed.
It has a wide range of applications in related fields, such as:
The third, fourth, and fifth harmonics of Nd: YAG lasers (355nm, 266nm, and 213nm, respectively)
The second and third harmonics of Ti: Sapphire amplifiers (400nm and 266.7nm), etc.
BBO electro-optic crystal has an extremely wide transmission range, a very low absorption coefficient, and a weak piezoelectric ringing effect.
Compared with BBO electro-optic crystals, it has the following characteristics:
Higher extinction ratio
Larger phase matching angle
Higher damage resistance threshold
Broadband temperature matching
Excellent optical uniformity
These are conducive to improving the stability of laser output power, especially in the triplet frequency of Nd: YAG lasers, which have many applications.
BBO electro-optic crystal can also be used in these fields:
OPO configurations
Optical parametric oscillators
Electro-optical applications from near-infrared to deep-ultraviolet
FEATURES
