摘要
The use of metal-oxide-SiO2 composite. to sustain random lasing in, ZnO thin films is proposed. It is shown that the presence of stripe pattern in the metal-oxide-SiO2 Composite is necessary to minimize lasing threshold and achieve directional emission. By controlling the concentration of the metal-oxide and stripe spacing, coherent lasing threshold and linewidth of similar to 85 kW/cm(2) and similar to 0.4 mn, respectively, can be obtained from mirrorless ZnO thin-film waveguide lasers.
