Abstract: A fractional handpiece and systems thereof for skin treatment including a handpiece body including a passively Q-switched laser assembly within the handpiece body operatively connected to a pump laser source to receive a pump laser beam having a first wavelength and a beam scanning system operable to scan a solid beam emitted by the passively Q-switched laser assembly and form a line of micro-beams across a segment of skin. The passively Q-switched laser assembly generates a high-power sub-nanosecond pulsed laser beam having a second wavelength. The pump laser source is a diode laser which emits the first wavelength at about 500 nm to about 1000 nm.

Abstract: A multiple frequency laser system and method for treating skin conditions via a handpiece features a pump laser module having a single laser beam at a first frequency. A dual laser module receives the laser beam at the first frequency and includes 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 receives as inputs the laser beam at the second frequency and the laser beam at the third frequency and is 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. The handpiece receives the laser beams from the frequency module and delivers them to skin for treatment.
