になる。Next, the operation will be explained. The fluorescent dye (2) excited by the 7-lush lamp (4) undergoes an S-'SK transition, emits fluorescence, and then absorbs light 1 again, changing the excited state to 'S'. Think about it. Before this excited molecule emits fluorescence for the second time and is transferred to S, the photon that was emitted earlier as fluorescence is converted into a molecule that is excited again. If this excited molecule were to return to the S state by emitting fluorescence due to the action, the number of photodeuterons would have doubled, including those that were spontaneously emitted earlier, to 2.

を外部にとり出したものがレーデ光源である。In this way, the light emitted earlier is confined within a certain range and sent back and forth. During this time, the Rade active molecules are exposed to UV light using a strong light source.
A Rede light source is a light source that is raised in an up-and-down position, and when the required intensity is reached, the light is extracted to the outside.
［発明が解決しようとする問題点Ｊ
従来のプラスチックレーザ素子は色素をプラスチックに
単に分散した構造であるので、′ＳからＴに湛移し、こ
こから色素が分解するという問題点があった。[Problem to be Solved by the Invention J] Since the conventional plastic laser element has a structure in which the dye is simply dispersed in the plastic, there is a problem in that the dye is transferred from 'S to T and decomposed from there.
この発明は上記のような問題点を解消するためになされ

ことを目的とする。This invention was made to solve the above-mentioned problems, and aims to provide a plastic laser element that can prevent fading of the fluorescent dye, extend its life, and at the same time improve luminous efficiency.

に、螢光収率の増加によりレーザ発光効率が向上する。[Function J] Since the fluorescent dye in this invention is encapsulated by cyclodextrin, it is easily dispersed in the polymer matrix even without a dispersant. In addition, the -multiplet state rapidly and abruptly transitions to the ground state due to an increase in fluorescence yield, and the probability of transition to the triplet state decreases, reducing photodecomposition of the dye. Furthermore, the laser emission efficiency is improved due to the increase in fluorescence yield.

効率が向上する。In the speed equation: sword shot=-'shikuyu'-[D] dt kO+kF+ksT, as l(F becomes larger, the fading speed of the dye decreases. Therefore, a plastic laser element with less fading due to a flash lamp is manufactured. In addition, the fluorescence yield is also 2 EC, and the laser emission efficiency is improved.
