Abstract

Solid-state organic waveguide dye lasers having distributed feedback (DFB) grating have several attractive features including minimal cost, easy fabrication, flexibility and compactness. These lasers exhibit several features of the broadband tunability, narrow-band lasing, and low threshold. Second harmonic generation (SHG) of yellow-red light from organic waveguide dye laser can achieve a novel tunable near-ultraviolet laser device based on organic material with the above-mentioned features. However, a conventional waveguide dye laser exhibit extremely low optical-optical efficiency, moreover, low output energy. Therefore, near-ultraviolet laser cannot be effectively generated by using conventional waveguide dye lasers. Development of high-efficiency, high-power organic waveguide laser is necessary to achieve a near-ultraviolet laser based on organic material.
