Noncollinearly phase-matched second harmonic generation (SHG) of Nd:YAG-laser light (1.064 $\mu$m) has been measured in a thin-film waveguide of stilbene-dye substituted methacrylate polymer on a glass substrate. The second-order nonlinear optical coefficient $d_{33}$ of the corona-poled film is $1.6\times 10^{-8}$ esu (at 1.064 $\mu$m). The phase-matching crossing angle of two guided fundamental beams is about 3.6° in the $1.38\pm 0.02$ $\mu$m-thick polymer waveguide. The SHG efficiency has been estimated to be about $5\times 10^{-5}$% for the fundamental peak power of about 130 W. The broad angular dependence of SH power has resulted from the short interaction length ($0.1\sim 1$ mm order) of two fundamental beams.
