Abstract:

In a study of CO2 laser pulsing techniques stable mode locking of a CO2 laser was achieved with the use of a resonated internal electro-optic phase modulator driven at frequencies near the axial mode interval. Pulses of 25 nanosecond duration and 147 nanosecond period were observed. Pulse trains at twice the fundamental mode frequency were also obtained. Stable locking was achieved with an r. f. input power to the modulator of less than 1 milliwatt. Locking could be induced when the modulation frequency was within plus or minus 130 kHz of the fundamental axial mode frequency.
