WHAT DOES PPLN CRYSTAL MEAN?

MgO:PPLN SHG crystals is usually fabricated with QPM grating durations appropriate for a variety of commercially offered pump laser wavelengths from 976 nm to 2100 nm, enabling era of frequency doubled mild in between 488nm and 1050nm.The poling duration of a PPLN crystal is decided because of the wavelengths of sunshine being used.
