DETAILS, FICTION AND BBO CRYSTAL

Sometimes, the mismatch might be small. Such as, whenever a β-BBO crystal is utilized to frequency double 1550 nm mild and supply 775 nm light-weight, the team velocity mismatch is just a few femtoseconds per millimeter.Nonetheless, it’s vital that you Observe that although BBO crystals can transmit UV light-weight, they ought to be dealt with
