Experimental Research of the Microwave Discharge Pumped CW Atomic Mercury Laser

In this paper, a kind of microwave-discharge pumped cw atomic mercury laser is introduced and demonstrated. In this experiment the laser is put in a microwave-guide, laser light is produced by means of microwave discharge. Whole dielectric medium, inner-cavity style, and co-axial structure are employed. 80 W microwave power is input in the microwave-guide, 30 W power is absorbed by the mercury medium. Laser cavity consists of 2 m spherical radius mirrors with reflectance of 999%. Laser wavelength is 5461 nm and its maximal power output is 01 mW. Light spot size is 3 mm with several transverse modes.
