Systems and method relate to administering phototherapy. A device includes a hollow structure having at least a first open end. The hollow structure includes a rotatable member, one or more coherent light generators, and, for each coherent light generator, one or more lenses or mirrors optically connected to the coherent light generator and configured to alter at least one aspect of a beam of coherent light. The device further includes a processing circuit including a processor and a memory storing instructions. The instructions, when executed by the processor, cause the processor to accept an input from an operator and generate one or more beams of coherent light according to a plurality of settings configured to produce a therapeutic effect at a targeted treatment site. Additionally, the rotatable member is configured to be rotated to direct the one or more beams of coherent light to the targeted treatment site.
