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.
Claims38
A laser system, comprising:
- a diode pump source;
- and
- a frequency doubled solid state visible laser pumped by the diode pump source, the frequency double solid state visible laser producing an pulsed laser output;
- and
- resources that provide instructions for the creation of the pulsed output that has a train of pulses with on and off times that provide for substantial confinement of thermal effects at a target site.
A method of treatment, comprising:
- providing a diode pumped, frequency doubled solid state laser system with a pulsed output that has a train of pulses with on times optimized for confinement of thermal effects;
- and
- directing a plurality of pulses to a target site, wherein a temperature rise at the target site is non-additive from pulse to pulse.
A method of treating biological tissue by laser surgery, comprising:
- providing a frequency doubled solid state visible laser system with a frequency doubler;
- providing instructions to the laser system to create a pulsed output that has a train of pulses with on and off times that substantially confine thermal effects;
- producing the pulsed output;
- and
- directing the pulsed output to a target site.
A laser treatment system, comprising:
- a diode pump source coupled to a frequency doubled solid state visible laser pumped by the diode pump source, the frequency double solid state visible laser producing an pulsed output;
- and
- a controller system responsive to a photodetector that provides instructions to the visible laser to create a pulsed output that has a train of pulses with on and off times that substantially confine thermal effects.
