Abstract:
A flashlamp-excited dye laser for producing a pulsed output beam of laser radiation having a long effective pulse duration, comprising:a pulse forming module electrically connected to a power supply, the pulse forming module generating in response to a trigger signal a series of spaced excitation pulses; a flashlamp electrically receiving the series of spaced excitation pulses from the pulse forming module, the flashlamp producing a series of light pulses in response thereto; a liquid dye medium receiving the series of light pulses from the flashlamp and, in response thereto, producing an output laser beam comprised of a series of spaced micropulses of laser radiation which, in combination, have a long effective pulse duration; a feedback module for measuring a portion of the output beam transmitted through a wavelength filter; and a tuning element in communication with the feedback module, the tuning element varying the wavelength of each micropulse in response to the measured portion of the output beam.
