FASCINATION ABOUT BBO CRYSTAL

Sometimes, the mismatch might be little. Such as, any time a β-BBO crystal is accustomed to frequency double 1550 nm mild and supply 775 nm light-weight, the group velocity mismatch is only a few femtoseconds for every millimeter.Nonetheless, it’s crucial to Take note that even though BBO crystals can transmit UV light-weight, they ought to be
