Highly Efficient Long-Lifetime Dual-Layered Waveguide Dye Laser Containing SiO2 Nanoparticle-Dispersed Random Scattering Active Media

We have demonstrated a highly efficient, long-lifetime waveguide dye laser using nanosized-particle-dispersed random scattering active media An experimental laser slope efficiency of 38.6% and energy threshold of less than 1 mu J at a single longitudinal mode were measured The operation lifetime of this laser device reached 6.5 million pump shots (C) 2009 The Japan Society of Applied Physics
