Abstract

Phase mismatch by angular detuning of a nonlinear crystal allows continuous variation of the intensity of second-harmonic light generated in the crystal, while maintaining a controlled phase relationship between the first and second harmonics. Interference of this second- harmonic light with second-harmonic light generated in another crystal further along the beam path has been measured, and can be understood by taking beam walk-off into account. When the second crystal is replaced by an optical fiber prepared for second-harmonic generation, the observed interference allows one to determine the phase of the (chi)⁽²⁾ grating in the optical fiber. We find the phase to be 88 +/- 4 degree(s). This phase differs by 180 degree(s) from recently reported results.
