Abstract:
A variable pulse duration, adjustable wavelength medical laser system, comprising:a solid-state laser for generating an input laser beam, including: a solid-state laser medium; an excitation source for pumping the laser medium, the excitation source being modulated to control pulse duration of the input laser beam; and a frequency doubler, disposed in a path of the input laser beam, for doubling the frequency of the input laser beam; a dye laser, for receiving the frequency-doubled input laser beam and for responsively generating an output laser beam of adjustable wavelength, the output laser beam having a pulse duration corresponding to the pulse duration of the frequency-doubled input beam; an output beam coupler, for optically coupling output beam to a delivery system configured to direct the output laser beam onto a biological tissue target; and a controller, coupled to the solid-state laser and the dye laser, including a user input device, adapted to adjust the pulse duration and the adjustable wavelength in response to user input specifying a pulse duration within a clinically relevant range of pulse durations and a wavelength within a clinically relevant range of wavelengths for a plurality of medical purposes.
