Abstract
A microchip laser and a handpiece including the microchip laser. The microchip laser includes a laser medium with input and output facets. The input facet is coated with a highly reflective dielectric coating at microchip laser wavelength and highly transmissive at pump wavelength. The output facet is coated with a partially reflective at microchip laser wavelength dielectric coating. A saturable absorber attached by intermolecular forces to output facet of microchip laser. A handpiece for skin treatment includes the microchip laser.
