A new class of glasses for second-harmonic generation

This paper shows that a cerium-doped lead phosphate matrix is a promising n ew base for glasses that possess a pronounced second-harmonic-generation ef fect for optoelectronic dataprocessing and -storage systems. The paper desc ribes the conditions for recording quadratic-susceptibility gratings in the lead-containing phosphate glass obtained by the authors with the so-far hi ghest efficiency for converting laser-radiation frequency into the second h armonic.
