Abstract

Progress in laser resonators and beam control requires new criteria for laser beam characterization, especially with spatial and longitudinal modes which tend to oscillate and are critical to their role as high power pump sources in solid state lasers. Previous papers by the author (K. J. Jones, 200f), (K. J. Jones, 2006) have applied wavelet-based phase extraction and adaptive wavelets to distortion correction in laser diode arrays. Adaptive optics aim at achieving greater dynamic stability in laser systems. This investigation examines multiple spatial and longitudinal modes in diode laser arrays and applies wavelets, first to determine the phase of the oscillating modes and adaptive wavelets to minimize mode distortion.
