Abstract
A beam delivery system for treating target tissue that includes an input for receiving a light beam, a variable attenuator for providing variable attenuation of the light beam, a power and wavelength detection assembly, a spot size adjustment assembly, and a controller. The power and wavelength detection assembly measures the power level of the beam, and detects when unwanted wavelengths are present in the light beam. The spot size adjustment assembly selectively feeds the beam through different optical fibers to achieve different spot sizes of the beam. The controller controls the variable attenuator, the power and wavelength detection assembly, and the spot size adjustment assembly to achieve the desired power and wavelength, and beam spot size.
