Abstract: A laser system that includes a diode pump source. A frequency doubled solid state visible laser is pumped by the diode pump source and produces a pulsed laser output with a train of pulses. Resources provide instructions for the creation of the pulsed output, with on and off times that provide for substantial confinement of thermal effects at a target site. This laser system results in tissue specific photoactivation (or TSP) without photocoagulation damage to any of the adjacent tissues and without causing full thickness retinal damage and the associated vision loss.

Abstract: A treatment apparatus for a tissue site includes a scattered light measurement device. The scattered light measurement device produces an excitation beam to scatter from the tissue site and monitors temperature dependent changes at the tissue site. An output device produces an output to an observer that is indicative of the temperature change at the tissue site. The output device can produce a variety of different outputs including but not limited an output through a computer, through a heads up display, through a slit lamp, an audible output or a print out of information.
