A slab Xe laser excited by a nonself-sustained discharge

摘要

Repetitively pulsed lasing with a high repetition rate of 10 - 20 kHz is oh tamed for the first time in the near-IR region from Xe atoms excited by a nonself-sustained dc discharge with preionisation by high-voltage pulses. For an active medium with dimensions 190 × 20 × 20 mm, the average output power was ～100 mW and the peak power was ～ 5 W. The relative intensity of lasing transitions can be controlled by varying the dc discharge input power and selecting the composition and pressure of a gas mixture.
