Increase in Laser Repetition Rate by Spectral Selection.

There is a need, particularly in optical computing applications, for an ultra high repetition rate, high power, modelocked laser source. Commercially available high power lasers can currently provide pulses up to 100 MHz repetition rates, which is at least a factor of ten less than is needed for many applications. An experimental and theoretical study has been made into the use of Fabry-Perot etalons as static repetition rate upconverters outside the laser cavity. We have shown both theoretically and experimentally that the output repetition rate can be increased up to twelve times while maintaining high average power.
