WHAT DOES BBO CRYSTAL MEAN?

Occasionally, the mismatch can be smaller. For instance, when a β-BBO crystal is accustomed to frequency double 1550 nm light-weight and provide 775 nm mild, the group velocity mismatch is only a few femtoseconds for every millimeter.Optical parametric chirped-pulse amplification (OPCPA): We use OPCPA to determine our items�?nonlinear conversi
