Abstract
We demonstrate a 2‐GHz tunability of the 385‐μm stimulated Raman transition of D2O vapor optically pumped by the 9R (22) transition of a tunable single‐mode CO2 TEA laser. Power levels of up to 800 kW in 100‐nsec pulses and conversion efficiency of CO2 laser energy to D2O laser energy at 385 μm of up to 0.4% have been obtained with a D2O oscillator cavity. The TEA CO2 pump laser, which consists of a grating and étalon tuned oscillator followed by an amplifier chain, produced 25‐J 100‐nsec single‐mode pulses and was tunable ±1 GHz around the 9R (22) line center. The present results indicate that tunable single‐mode pump lasers are necessary in order to optimize high‐power optically pumped laser systems and to produce narrow‐linewidth spectral characteristics.This publication has 11 references indexed in Scilit:
