Standard Specifications
Available Optical Coatings



- BBO most striking advantages occur in average power applications. It is an order of magnitude more resistant to thermal fracture than those other nonlinear materials (LiIO3, LiNbO3, KDP).
- BBO has a low-temperature sensitivity for doubling 1064 nm and it can be used in a quadrature configuration.
- BBO is a relatively poor thermal conductor, but this is offset by the wide range of transparency, and in particular by the lack of any intrinsic absorption at 1064, 532, 355 and 266 nm.
- The transparency of BBO in the UV and IR, coupled with its high birefringence, permits phase matching for a variety of optical parametric amplifies generating tunable radiation in the visible and near IR.
- BBO requires high peak powers and high quality beams to be efficient. On the other hand, it has a high resistance to optical damage, and this leads to smaller crystal size.
