摘要： An optical pulse source comprising a DPSS pump laser, a photonic crystal fiber (PCF), and acousto-optic modulator (AOM) gating device is disclosed. The pump pulses are coupled through lenses to the AOM gating device, which is synchronized to the pump laser and is operable to gate the pump pulses to a reduced repetition rate Rr=Rf/N, where Rf is the pump laser fundamental frequency. The pulses from the AOM are injected via optics into the PCF. Propagation through the PCF causes the pulses to broaden spectrally to produce optical supercontinuum pulses. An optical pulse source that further includes an acousto-optical tunable filter (AOTF) operable to convert the optical supercontinuum pulses into wavelength variable output pulses is also provided. A method of scaling the energy of the optical supercontinuum pulses is also disclosed.

摘要： Amplifying optical waveguide devices, which, by combining an instantaneous or nearly instantaneous gain medium with pulsed cladding-pumping can convert the multimode pump pulses to higher-brightness (even single-mode) signal pulses. The operating parameters can be carefully matched to the interaction length of the amplifying optical device to promote efficient conversion. The invention combines attractive features of cladding-pumped waveguide devices such as robustness and good thermal management properties with those of synchronously pumped devices. Thus, the pulse energy of the generated beam is not limited by the energy that can be stored in the gain medium.
