美国贝尔实验室李天培等人发现把普通的1.3μm BH激光器,再解理制作成短腔(50～150μm)折射率导引激光器,在CW和调制两种情况下均能提供改进的单频输出。
Li Tianpei and others at Bell Labs of the United States found that the conventional 1.3 μm BH laser can be re-cleaved into a short cavity (50-150 μm) index guided laser to provide an improved single-frequency output in both CW and modulation .
