EVERYTHING ABOUT BBO CRYSTAL

In some cases, the mismatch may be smaller. For example, whenever a β-BBO crystal is used to frequency double 1550 nm gentle and provide 775 nm light-weight, the team velocity mismatch is only some femtoseconds for each millimeter.The difficulty that arises when utilizing ultrashort pulses for 2nd harmonic technology (SHG) is the fact shorter pu
