超高密度DVD用蓝光半导体激光器的发展

摘要

DVD recorded density is mainly limited by laser wav elength, It is important to study short-wavelength laser for super high density DVD system. Several short-wavelength blue laser's characters and applications are introduced in the paper.%激光波长是限制DVD记录密度提高的关键因素,研制短波长激光器是超高密度DVD用光源的重要发展方向.这里介绍几种短波长蓝光激光器(如GaN、ZnSe、S HG等)的特点及应用展望.
