Abstract

Solid-state waveguide dye lasers including distributed feedback (DFB) grating have several attractive features including minimal cost, easy fabrication, flexibility and compactness. And thus, they are suitable for a laser spectroscopy, because of its broadband tenability and narrow-band lasing, and low threshold. In recent years, several researchers have presented the laser oscillation of organic waveguide lasers in the wavelength region from near ultraviolet to near infrared. However, the slope efficiency was limited to only 1-2%.
