We generate broadband pulses covering the Yb: and Tm:silica amplification ranges with a passively phase-locked front end based on Er:fiber technology. Full spectral coherence of the octave-spanning output from highly nonlinear germanosilicate bulk fibers is demonstrated. Seeding of a high-power Tm: fiber generates pulses with a clean spectral shape and a bandwidth of 50 nm at a center wavelength of 1.95 mu m, pulse energy of 250 nJ, and repetition rate of 10 MHz.

Abstract
We generate broadband pulses covering the Yb: and Tm:silica amplification ranges with a passively phase-locked front end based on Er:fiber technology. Full spectral coherence of the octave-spanning output from highly nonlinear germanosilicate bulk fibers is demonstrated. Seeding of a high-power Tm: fiber generates pulses with a clean spectral shape and a bandwidth of 50 nm at a center wavelength of 1.95 mu m, pulse energy of 250 nJ, and repetition rate of 10 MHz.
