Am asymmetric ring laser
Lin Fucheng, Li Shi fang, and Hu Qiquan
Asymmetric output is obtained when a feedback is introduced in a ring laser to force part of the traveling wave into the other. The coupling between both waves plays an important role in such a device, The output rotio of the traveling wave- is obtained experimentally to be 40 for a Ou vapor laser and 60 for a dye lase
