THE DEFINITIVE GUIDE TO A-BBO CRYSTAL

The crystal axis is c. The Main ray is parallel towards the way utilized to measure the tuning angle (θ), which is optimized during section matching. Conversion efficiency is optimized for rays parallel for the Main ray and even worse for rays at larger angles (ψ) to your Main ray.Beta Barium Borate (BBO) crystals have been a subject of fascinati
