Scaling Of An Optically Pumped Mid-Infrared Rubidium Laser, Paul J. Moran

Theses and Dissertations

An optically pumped mid-infrared rubidium (Rb) pulsed laser has been demonstrated in a heat pipe along the 6²P_3/2 - 6²S_1/2 transition at 2.730 µm and the 6²P_1/2 - 6²S_1/2 transition at 2.790 µm. The bleached limit, slope efficiency, and maximum laser output energy of the mid-IR Rb laser have been shown to scale linearly with increasing Rb density, contrary to prior laser demonstrations. A maximum output energy of 5 nJ per pulse had previously been observed before a rollover occurred in the scaling of output energy with Rb …
