| Abstract: | Some technical problems related to output power stability of 3 391 nm He-Ne laser were discussed.The cavity structure of the laser was designed;and discharging parameters and stability was investigated.Under the conditions that the ration between the reflector＇s curvature radius and the cavity length is 1.6,and the effective discharge length is 0.2 m,a measured 1.72 mW of the multimode continuous laser＇s output power was obtained,and the beam divergence angle of which is 6.43 m rad.The output power variation is <2% when optical feedback technique was used. |
