Abstract: A continuous wave laser is provided to produce isolated surgical effects within selected tissue layers. The continuous wave laser includes a laser source, an optical modulation device, and a system controller. The laser source produces a laser beam which is provided to the optical modulation device. The optical modulation device modulates the laser beam in order achieve isolated surgical effects within selected tissue layers. The system controller drives the laser source and the optical modulation device to achieve the isolated surgical effects. The system controller may direct the laser beam delivered to the selected tissues comprise a series of modulated bursts which further comprise modulated micro bursts. These bursts and micro bursts may be modulated in amplitude, duration and separation.
