OSCILLATION WAVELENGTH VARIABLE ORGANIC DISTRIBUTION FEEDBACK TYPE LASER

摘要

PROBLEM TO BE SOLVED: To create a high performance organic distribution feedback type laser by using the grating forming characteristics of optical inducing substance moving materials, and to realize an oscillation wavelength variable organic distribution feedback type laser by using the characteristics of azobenzene polymer capable of erasing/rewriting the grating. SOLUTION: This organic distribution feedback type laser is provided with a resonator in a double layer structure constituted of an optical inducing substance moving material layer and a dye layer in the lower layer of the material layer. This organic distribution feedback type laser is characterized in that an oscillation waveform can be made variable by changing interference exposure conditions to the optical organic substance moving materials being polymer substances having the azobenzene frame of this formula.
