Abstract

An experiment is reported which relates the gain characteristics of the pulsed mode in a neodymium-doped silicate glass laser to the giant-pulse laser energy output. In this experiment optical pumping of both the pulsed and giant-pulse mode occur in a time short compared to laser atom metastable lifetime. An analysis of the experimental data shows that pulsed-mode gain characteristics can be related to the giant pulse energy output through the use of a model for the giant-pulse laser similar to that derived by Wagner and Lengyel provided that corrections are included to account for the effects of resonator standing waves and gain variations across the radius of the laser rod.
