Abstract:
A flashlamp-excited pulse dye laser system generating light pulses for therapy, comprising:an optical system defining a resonant cavity and providing at least a portion of light generated in the resonant cavity as an output laser light pulse; a cell for containing a laser gain media in the resonant cavity; a flashlamp for exciting the laser gain media contained in the cell; a circulator for circulating the laser gain media through the cell; a controller for triggering the flashlamp to excite the laser gain media while the circulator is circulating the gain media through the cell to generate a long effective laser light pulse, comprising a series of shorter-duration subpulses, having duration of greater than one hundred microseconds; and a medical delivery system for transmitting the output laser light pulse to tissue of a patient.
