Description

Construction and measurement of an experimental He-Se laser are described. Laser tube configurations are improved to prevent the Se vapor from diffusing toward the Brewster windows.<br> The laser, which has an effective discharge region of 70cm in length and 2.8mm in diameter, yields 23mW on 11 lines lasing simultaneously.<br> Saturation current of a He-Se laser is considerably higher than that of a He-Cd laser and reaches up to 220_??_460mA with oven temperatures between 210° to 250°C.<br> This result is attributed to the energy difference between Hell (2S1/2) and He (3S1), which are used for the excitation of SeII and CdII, respectively.<br> We have mainly analyzed the relation between Se density nse (temperature) and saturation current IS and it has turned out that Is2 is linear to nse with a good approximation. By selecting with a prism, we obtained a few mW power output in each of the 4976, 4993, 5068, 5176, 5228, 5305 Å lines.
