BBO CRYSTAL FUNDAMENTALS EXPLAINED

Occasionally, the mismatch might be little. One example is, every time a β-BBO crystal is accustomed to frequency double 1550 nm mild and provide 775 nm light, the group velocity mismatch is only a few femtoseconds for every millimeter.The issue that arises when working with ultrashort pulses for second harmonic technology (SHG) is always that s
