ABSTRACT:
A flashlamp-excited dye laser generates a pulsed output beam having a long pulse duration. The laser includes a pulse forming circuit which generates an excitation pulse having an amplitude which generally increases in coordination with the lasing threshold for the flashlamp-excited dye laser. The flashlamp-excited dye laser is driven with the pulse to produce a pulsed output beam of laser radiation of at least 500 microseconds in duration.
