Abstract
An apparatus and method are provided for producing an ultrashort pulsed output beam. A 694 nm pump beam from a first GaN semiconductor laser diode pumped, Q-switched ruby laser is directed into at least one amplifier that includes a broadband gain element doped with trivalent chromium ions (Cr). A spectrally linearly chirped low-intensity seed pulse from a master oscillator is directed into the at least one optically pumped amplifier to produce an amplified linear chirped pulsed output beam. A 694 nm second pump beam from a second GaN semiconductor laser diode pumped, Q-switched ruby laser is directed into a power amplifier that also includes a broadband gain element doped with trivalent chromium ions (Cr). The amplified linear chirped pulsed output beam is directed into the optically pumped power amplifier to produce a high energy linear chirped pulsed output beam which is then directed into a pulse compressor to produce the ultrashort pulsed output beam.
