Synthetic Research on Laser Electro-Optics and Quantum Electronics System

本项目的主要任务是综合掌握量子电子学领域的研究现状，安排研究项目，为在日本举行的国际量子电子学大会(IQEC‘88)作准备。对于激光应用，波长更短的激光器正在开发中。1987年11月，在大阪大学召开了短波激光及其应用国际研讨会。作为激光能源应用的一种，激光同位素分离的研究是在大阪阿尔维斯大学物理化学研究所、大阪阿尔维斯大学激光技术研究所和激光工程研究所进行的。研制了适用于铀同位素分离的激光器，并对铀同位素分离的基本过程进行了研究。激光同位素分离系统的总体理想设计已经完成。为了提高准分子激光器的质量(高功率、长寿命)，对材料加工的工业应用具有重要意义的准分子激光器进行了研究，并取得了丰硕的成果。东京大学开发了高质量的半导体激光器，在振荡模式控制方面取得了很大进展。作为其应用，CLDO介绍了光信号处理(大阪大学)和超板条波长激光器(大阪大学)的研究，高分辨率光谱的发展是在东京大学进行的。此外，准分子激光在医学上的应用(近海大学)、分子快弛豫现象的观察(分子科学研究所)、XUV激光器的振荡(大阪大学)。已经取得了很大的进步。

The main item of the present project is to grasp synthetically the status qua of the research activity in the field of quantum electronics, to arrange the research items and to help the International Quantum Electronics Conference (IQEC '88) to be held in Japan. For laser applications, shorter wavelength lasers and being developed. In Nov. 1987,the International Symposium on Short Wavelength Lasers and their Applications was held at Osaka University, and the research status qua in the world was investigated.As one of laser energy applications, the research on laser isotope separation is done at "the Institute of Physical and Chemical Research (IPCR)"for MLIS, and at the Institute for Laser Technology and the Institute of Laser Engineering, Osaka University for ALVIS. Laser adequate for uranium isotope separation have been developed and the fundamental process in the isotope separation has been investigated. General ideal design for laser isotope separation system was already done.To improve the quality (high power, long lifetime) of the excimer laser, which is important for the industrial applications of material processing, is investigated at the Institute for Electrical Technology, IPCR and Keio University and the fruitful results were obtained.High quality semiconductor laser was developed at Tokyo University, and the control of oscillation mode has been made great progress. As its applications, the researches on optical signal process (Osaka Univ.),and generation of super slab wavelength laser (Osaka Univ.),were presented in CLDO.Development of high resolution spectroscopy were done at Tokyo Univ. and Kyoto Univ., and its application to nuclear spectroscopy can be expected.In addition to the above, the excimer laser application to medical (Kinki Univ.), observation of fast relaxation phenomena in moleculars (Institute for Molecular Science), the oscillation of XUV laser (Osaka Univ.) have been made great progress.
