Abstract
Inserting an As2S3 optical fiber into a coupling-hole of one of the optical resonator mirrors directly, a pig-tail type CO laser is successfully demonstrated on its fundamental operational characteristics, together with theoretical treatments. First, finding the spatial intensity-distribution on the coupling-hole mirror, its effective transmittance vector t is evaluated in comparison with the measured spatial beam profile. Then, the output power is measured with the various coupling-hole mirrors, obtaining the maximum output power at the coupling-hole diameter of approximately 0.6 mm. These characteristics of the output power vs the coupling-hole diameter are theoretically explained by using the gain parameters G and the internal loss vector ai obtained, being well consistent with the experiments. As a result, the optimum coupling-hole evaluated is quite suitable to compose the pig-tail type scheme.
