Modulation of a CO 2laser by plasma injection into the cavity
Abstract
Observations of simultaneous Q-switching and mode-locking have been made in a TEA CO 2 laser when a low density underdense plasma was injected into the cavity. The plasma which was produced in an electromagnetic shock tube had a density ≈10 17 cm -3. A likely mechanism for mode-locking is the time dependent plasma refractive index leading to phase perturbation.
