This study evaluates the effects of beacon-wavelength mismatch on phase-compensation performance. In general,
beacon-wavelength mismatch occurs at the system level because the beacon-illuminator laser (BIL) and high-energy
laser (HEL) are often at different wavelengths. Such is the case, for example, when using an aperture sharing element to
isolate the beam-control sensor suite from the blinding nature of the HEL. With that said, this study uses the WavePlex
Toolbox in MATLAB® to model ideal spherical wave propagation through various atmospheric-turbulence conditions.
To quantify phase-compensation performance, we also model a nominal adaptive-optics (AO) system. We achieve
correction from a Shack-Hartmann wavefront sensor and continuous-face-sheet deformable mirror using a least-squares
phase reconstruction algorithm in the Fried geometry and a leaky integrator control law. To this end, we plot the power
in the bucket metric as a function of BIL-HEL wavelength difference. Our initial results show that positive BIL-HEL
wavelength differences achieve better phase compensation performance compared to negative BIL-HEL wavelength
differences (i.e., red BILs outperform blue BILs). This outcome is consistent with past results.
