Paper Abstract

A prediction is made that, for small values of turbulence (L sub 0) in the range of 20-40 cm, ground-based laser beams at near infrared can be focused to diffraction limited accuracy on targets in space without using adaptive optics or other wavefront correction procedures. It is found that, at infrared wavelengths, resolution is more likely to be limited by the telescope size and aberrations than by atmospheric turbulence. By building large enough telescopes to diffraction limited standards rather than currently accepted standards which fall well short of this limit, there is almost no limit to achievable resolution.
