A portable, small-footprint laser device contains one or more housings in which a laser energy source and an optical arrangement are disposed. The housing produces a laser beam spot that may be rotated and scanned to apply laser energy to a target area. The laser device receives treatment parameters and uses them to program a treatment regimen in which activation and movement of the housings is automated. The laser device may be used to apply a treatment regimen to a patients hands or feet that are infected by Onychomycosis. In the treatment regimen, certain wavelengths of laser energy are applied at a predetermined duration. The treatment may be repeated, and a topical anti-fungal medication may be applied to aid in the efficacy of the treatment.
