We investigate the possibility of improving the beam quality and obtaining high conversion efficiency in nonlinear sum-frequency generation. A 765 nm beam from an external cavity tapered diode laser is single-passed through a nonlinear crystal situated in the high intracavity field of a 1342 nm Nd:YVO4 laser, generating a SFG beam at 488 nm.

The ECDL have MH^2=1.9 and MV^2=2.4 and the solid-state laser has M^2
