M. Kiguchi et al., A NEW MEASUREMENT OF 2ND-HARMONIC GENERATION EFFICIENCY, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 227, 1993, pp. 133-142
A new method of measuring second-harmonic generation efficiency using
powder crystals is demonstrated. The second-harmonic wave generated wi
th the evanescent wave (SHEW) is phase-matched for every material. The
efficiency of the second-harmonic generation can be estimated from th
e SHEW power, regardless of the phase-matchability of the material in
a bulk crystal, even when powder crystals are used as the sample.
