Abstract

We have demonstrated that ultra-lightweighted telescope primaries of nominal surface figure can be used to generate diffraction limited beams for laser communications. Compensation for optical surface misfigure was provided by a phase conjugating mirror to construct a phase conjugated transmitter subsystem. For our demonstration we matched a cw 514 nm beam with a self pumped photorefractive phase conjugating mirror. (Laser diode beams at 820 nm are also well matched to this phase conjugating mirror [1].) Using a primary with an RMS surface misfigure of μ/3, we produced a six inch beam with an RMS OPD of λ/17.
