Abstract:
A method includes accumulating optical pump power in a first laser gain medium during a first period of time, where the first laser gain medium is optically located within a resonator. The method also includes providing at least some of the accumulated optical pump power as a first laser output with a feedback-controlled waveform from the first laser gain medium to a second laser gain medium during a second period of time, where the second period of time is substantially shorter than the first period of time. The method further includes generating a second laser output having a burst of laser pulses using the second laser gain medium as a power amplifier. The first and second laser outputs have higher power levels during the second period of time compared to a power level of the optical pump power during the first period of time.
