Recently, various kinds of solid-state tunable lasers have been developed. In the next stage, however, it is a very important item to develop integrated tunable lasers in which all components are integrated on a chip including a pump source and tuning elements. As the first step of the project, we tried to develop a waveguide dye laser with a plastic film, and made a fundamental research on the fabrication of an optical waveguide with inorganic crystals.The main results of this project for two years are summarized as follows.1. We realized an integrated distributed feedback (DFB) dye laser with Rhodamine 6G doped PMMA thin film pumped by a Nd : YAG laser. 2. Using the spiking effect of the DFB waveguide dye laser developed above, we generated a single ultrashort pulse with a duration of tens ps, and proposed a new integrated-type pulse compressor which can compress the pulse to the fs region. 3. Using the pulsed laser deposition (PLD) method, we fabricated BaTiO3 and Ti : sapphire films, and evaluated the optical property of them which are useful for integrated tunable laser devices.

近年来，各种固态可调谐激光器得到了发展。然而，在下一阶段，开发集成可调谐激光器是一个非常重要的项目，其中所有组件都集成在一个芯片上，包括泵浦源和调谐元件。作为该项目的第一步，我们尝试了塑料薄膜波导染料激光器的研制，并对无机晶体光波导的制作进行了基础性研究，两年来的主要成果如下：1.利用Nd：YAG激光泵浦的若丹明6G掺杂PMMA薄膜实现了一种集成分布反馈染料激光器。2.利用上述DFB波导染料激光器的尖峰效应，我们获得了脉宽为几十ps的超短脉冲，并提出了一种新型的集成脉冲压缩器，可以将脉冲压缩到fs范围。3.采用脉冲激光沉积（PLD）方法制备了BaTiO_3和Ti：Sapphire薄膜，并对它们的光学性质进行了评价。
