Abstract

We derive an expression for the wavelength (lambda) _o giving maximum resolution for an adaptive-optics compensated telescope. An approximate expression for average on-axis intensity is written to account for the competing effects of diffraction and residual (post-compression) phase error; this expression is then differentiated with respect to the imaging wavelength (lambda) to yield (lambda) _o. The analytically predicted (lambda) _o is compared to simulation results and correspondence is shown to be good at widely separated seeing conditions and adaptive optics geometries.
