Abstract
A source of femtosecond pulses at center wavelengths of about 940 nm and about 1140 nanometers (nm) includes a mode-locked fiber MOPA delivering pulses having a center wavelength of about 1040 nm. The 1040-nanometer pulses are spectrally spread into a continuum spectrum extending in range between about 900 nm and about 1200 nm and having well defined side-lobes around the 940-nm and 1140-wavelengths. Radiation is spatially selected from these side-lobes and delivered as the 940-nm and 1140-nm pulses.
