A mid-infrared supercontinuum (SC) is generated in ZBLAN ( ZrF 4 BaF 2 LaF 3 AlF 3 NaF ) fluoride fibers from amplified nanosecond laser diode pulses with a continuous spectrum from 0.8 μ m to beyond 4.5 μ m . The SC has an average power of 23 mW , a pump-to-SC power conversion efficiency exceeding 50%, and a spectral power density of 20 dBm nm over a large fraction of the spectrum. The SC generation is initiated by the breakup of nanosecond laser diode pulses into femtosecond pulses through modulation instability, and the spectrum is then broadened primarily through fiber nonlinearities in 2 7 m lengths of ZBLAN fiber. The SC long-wavelength edge is consistent with the intrinsic ZBLAN material absorption.
