Paper Abstract

Solid-state dye lasers have been developed as compact and easy-to-handle coherent light sources. In particular, distributed feedback (DFB) solid-state dye lasers are able to emit narrow-banded single-mode laser beams. In DFB lasers, the diffraction grating is a key device for selecting the laser oscillation wavelength from a fluorescent band of organic dye. We adopted an "etchless process" and fabricated gratings for DFB solid-state dye lasers quickly and at low cost. In this study, we attempted to fabricate a multi-beam DFB solid-state dye laser combining pitch-different gratings and dye-doped silica xero-gel. We succeeded at obtaining narrow-banded triple-beam laser oscillations in the same optical axis with the three-wavelength DFB solid-state dye laser device.
