Optimum operation of an unified mini-optically pumped NH3 submillimeter wave laser

摘要

An unified miniature optically pumped NH3 submillimeter wave laser (OPSMMWL), including a mini TEA-CO_2 pump laser, was developed. It lased successfully with coherent emission at 67.2 µm, 90.4 µm and 151.5 µm. The optimum operation of the unified mini-OPSMMWL was studied experimentally and the relations among SMMW laser output power, operating gas pressure, length and coupling condition of the cavity were measured. It has been found that buffer gas N_2 has significant effect on 67.2 µm and 151.5 µm emissions and very wide band SMMW laser emission was a common feature of the mini-OPSMMW cavity laser.
