Abstract

In this work, the hybrid configuration was used to produce the single longitudinal mode operation of pulsed CO₂ laser with 14 cm long active volume at the pressure 3 atm. For this resean, a low pressure continuous wave CO₂ laser with 120 cm long active volume is used. It was found that the emitted pulses of the system exhibit single mode behavior in above threshold condition and also at the pressures up to 7 mbar below threshold condition. To characterize the system performance, various parameters of the single mode pulses at different pressures and powers of the continuous wave laser were analyzed. Furthermore, the threshold pressure of the continuous wave laser for the single mode operation was obtained at about 9.5 mbar. It is shown that in both above and below threshold conditions, the single mode pulses have higher durations and rise times and also lower build- up times.
