WHAT DOES BBO CRYSTAL MEAN?

Occasionally, the mismatch can be small. For example, when a β-BBO crystal is utilized to frequency double 1550 nm light and supply 775 nm light-weight, the team velocity mismatch is only some femtoseconds for every millimeter.When selecting an SHG crystal, the pulse duration from the laser source should be taken into account.
