Fractional handpiece with a passively Q-switched laser assembly

A fractional handpiece for skin treatment comprising:

• a handpiece body comprising:
• 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, the passively Q-switched laser assembly comprising one or more pump lenses and a laser cavity comprising one or more external mirrors;
• a beam splitting assembly operable to split a solid beam emitted by the passively Q-switched laser assembly and form an array of micro-beams across a segment of skin;
• and
• a positional sensor operable to guide movement of the fractional handpiece and to synchronize with laser pulsing,
• wherein the passively Q-switched laser assembly generates a high power sub-nanosecond pulsed laser beam having a second wavelength.
