Induced χ(2) gratings in glasses
Zel'dovich B. Ya., Kapitskii Yu. E., Churikov V. M.
Second-harmonic generation in a glass has been observed. The angular selectivity of the^(2) grating has been measured. The decay and restoration of gratings have been observed. The conversion efficiency is 10 ~ 6 over a distance of 60μιη at an average optical power of240 m W.
