Abstract
In a CO2 gasdynamic laser (GDL), a small signal gain and an output of 16 μm have been theoretically examined in detail by solving the rate equations with the population of each vibrational level against the 9.4-μm stimulating field. The eight levels of CO2 up to the (001) level including the (110) and the (030) levels, and the 31 reactions involving the V-T reactions are taken into account in this model. With a 9.4-μm [P(14)] pulse of 10-MW input power, 8-mm-diam spot size, and 100-nsec pulse width, a 16-μm [P(15)] pulse of 27-μJ/pulse/cm3 extractable energy and 5.7-kW maximum power is obtained from an active length of 0.1 m. It indicates that by using a Q-switch technique, high-repetition-rate operation of 200 kHz can produce an average output power of 5 W/cm3. Finally, a 16-μm continuous lasing by injecting the 9.4-μm beam continuously is analyzed.
