摘要：

We have investigated the second harmonic conversion efficiency of broad-band Nd: glass laser light (Δν/c < 30cm−1FWHM). Using two KDP crystals in a quadrature arrangement we obtain energy conversion efficiencies ~ 55 percent with an initial bandwidth for the fundamental of Δν/c ~ 17 cm −1 FWHM. For these conditions, we observed a modest increase (~ 70 percent) in the harmonic bandwidth (FWHM) relative to the fundamental. The usual theory of three-wave mixing in dispersive birefringent nonlinear crystals is extended to describe the broad-band harmonic conversion process; the generalized theory includes the statistical properties of the light and phase mismatch effects on the spectral components in the complex field amplitudes. Good agreement is shown between the code calculations and the measurements. © 1990 IEEE
