ABSTRACT:
Applicants have discovered that the conversion efficiency of doped glass optical second harmonic generators can be enhanced when the frequency .omega. of the fundamental beam or the frequency 2.omega. of the harmonic beam is chosen near the resonance frequency of an optical transition in the dopant. This resonant enhancement is demonstrated for Tm doped aluminosilicate glass fibers where tuning of the fundamental writing beam to a resonance frequency enhances the second harmonic output by a factor of 10.sup.3.
