THE RUBY LASER: PUMPED BY A PULSED ARGON ION LASER

Abstract
A ruby laser with a pulsed argon ion laser as a pump was constructed and operated at 77° and 300°K. Threshold for oscillation was ∼13 mJ. A unique type of Q‐switched operation was observed that produced pulses of ∼15 nsec at 300°K and ∼6 nsec at 77°K.
