Abstract
We have observed the reflected second-harmonic intensity generated by an incident beam which is totally reflected by the nonlinear medium immersed in a denser linear medium. The reflected intensity becomes very high near the critical angle for total reflection. The role of momentum matching for the reflected intensity is demonstrated.
