Lasers capable of lasing at at least two wavelengths are provided having a lasing medium which is capable of lasing at a first wavelength and at a second wavelength. An output coupler is positioned along a longitudinal axis at a first end of the lasing medium and a first mirror, movable beam block shutter and a second mirror are positioned sequentially along the longitudal axis of the lasing medium at a second end of the lasing medium. The first mirror is highly reflective at a first wavelength, and the second mirror is highly reflective at a second wavelength while being transparent at he first wavelength. By selectively positioning the beam block shutter in the longitudinal axis of the lasing medium, the lasing wavelength can be selected. Also provided are laser workstations having two lasers driven by a single electronics drive system in which a single energy storage network is connected to a first laser pump chamber oprative to excite a second Imedium. Also provided are methods of treating skin using multiple wavelengths of energy. |
