In this research we can emphasize that theoretically basic processes of amplification in the novel dye-doped plastic fiber amplifier is analyzed at the begining. Namely absorption and emission cross-sections of dye molecules in the fiber at low concentration were measured and they are used analysis of the rate equation of three level system. For example as the result of the analysis for Rhodamine dyes may give amplifications from hundred to two thousand times. Grating structures in the fiber may give unified functions between amplifier and oscillator. We are trying to realize this type of device from the basic point of view. We already observed the narrowing of light from the end of the fiber. In the world wide researchs of silica optical fibers also fabrications of various grating structures are very exciting now. Those kinds of our researchs occupied monopolised position in the field. Waveguide type ring laser was also studied by coumarin dye at blue light range. The evidence of lasing was confirmed by spike-like emission in spectra. Light amplification for medical use was also proposed.New type of photo-dynamic process may surpress of kill the cancer tissue with a new photo-activating pharmacy. This study is promissing.

在本研究中，我们可以强调的是，从理论上分析了新型掺染料塑料光纤放大器的基本放大过程。即测量了染料分子在低浓度下在光纤中的吸收截面和发射截面，并用它们分析了三能级系统的速率方程。例如，根据对罗丹明的分析结果，染料的放大倍数可能在100到2000倍之间。光纤中的光栅结构可以在放大器和振荡器之间提供统一的功能。我们正试图从基本的角度实现这种类型的设备。我们已经观察到从光纤末端发出的光变窄了。在世界范围内，石英光纤的研究也是非常令人兴奋的，各种光栅结构的制作也非常令人兴奋。我们的这类研究在该领域占据了垄断地位。用香豆素染料研究了蓝光波段的波导型环形激光器。光谱中的尖峰发射证实了激光的存在。新型的光动力过程可以通过一种新型的光激活药物来抑制或杀灭肿瘤组织。这项研究是有希望的。
