Spontaneous self‐pulsing has been observed in a 10.6‐μ CO2 laser, Q‐switched in ≈10 nsec by an internal GaAs electro‐optic cell, with no saturable absorber present. Each Q‐switched event consists of a train of ten or more 20‐nsec pulses with a total duration of ≈400 nsec in a single P(20) line. Electro‐optic dumping of the cavity energy near the peak of oscillation gives a single output pulse of ≈10‐kW peak power and 25‐nsec duration. A numerical comparison is made with the circulating π pulse… CONTINUE READING
