Multiple frequency laser system for treating skin conditions

A multiple frequency laser system for treating skin conditions comprising:

• a handpiece for treating skin conditions;
• a pump laser module having a single laser beam at a first frequency;
• a dual laser module receiving the laser beam at the first frequency and including dual free running laser resonators to produce a laser beam at a second frequency and a laser beam at a third frequency;
• a frequency conversion module receiving as inputs the laser beam at the second frequency and the laser beam at the third frequency and configured to selectively provide laser beams to the handpiece including a second harmonic generation of the second frequency, a second harmonic generation of the third frequency, a summed frequency generation of the second frequency and the third frequency, the laser beam at the first frequency, the laser beam at the second frequency, and/or the laser beam at the first frequency combined with the laser beam at the second frequency;
• and
• the handpiece receiving the laser beams from the frequency conversion module and delivering them to skin for treatment with solid beam of variable size, a fractional microbeam pattern, or a hybrid beam pattern of a solid beam and fractional microbeams.
