Abstract
Generalized beam matrices II. Mode structure of lasers and periodic
misaligned complex optical systems
A generalized beam matrix method is used to investigate the mode structure
of astigmatic misaligned optical systems with loss or gain. In these optical
systems the usual real-argument polynomial-Gaussian beams are not eigenfunctions,
and off-axis complex-argument polynomial beams must be used. New beam transformations
for these complex-argument modes are reported. Stability criteria are developed,
and mode selection in laser resonators that contain tilted, displaced,
or curved complex optical elements is discussed.
