Abstract

Side-pumped lasers such as flashlamp- or reactor-pumped lasers often have a nonuniform energy deposition in the gain medium, which can establish a significant transverse index gradient. This gradient significantly complicates energy extraction. A normalized resonator analysis method is developed that predicts resonator stability transitions and mode sizes for parabolic index fields. Parameter studies for some practical classes of resonators are presented, along with some design guidelines. Experimental comparison for a long-pulse gas laser shows good agreement with stability transition times. Two resonator-design approaches are presented for increasing the extraction efficiency in the presence of intracavity index gradients.
