THE SINGLE BEST STRATEGY TO USE FOR A-BBO CRYSTAL

The crystal axis is c. The Main ray is parallel into the way used to measure the tuning angle (θ), that's optimized throughout phase matching. Conversion performance is optimized for rays parallel on the chief ray and worse for rays at larger angles (ψ) to your Main ray.Regretably, it could be very difficult to compare the LIDT specification of a
