摘要：

Here we report the random laser emission from surface corrugated waveguides. Discrete lasing modes, super narrow spectral linewidth, and the existence of lasing threshold behavior have been observed. Single mode emission was observed by controlling the gain length. The lasing modes are strongly polarized. A theoretical model was presented to explain the localization phenomena.
