We report on the generation of a high average power, flat supercontinuum using a compact ytterbium-doped fiber amplifier. The femto-and picosecond pulses delivered by the amplifier are coupled into two different photonic crystal fibers. By using picosecond pulses the highest output power of 5 W with
An assortment of photonic-crystal fibers with a core area varying from 20 to 50 ΞΌm^2^ is used to demonstrate efficient frequency conversion of megawatt femtosecond Cr:forsterite laser pulses with a central wavelength of 1.24 ΞΌm into the visible and infrared spectral ranges. Supercontinuum radiation
A passively mode-locked ytterbium-doped largemode-area photonic crystal fiber oscillator operating in the vicinity of zero cavity dispersion is demonstrated. The self-starting mode-locking operation is achieved by a high contrast saturable absorber mirror. Two mode-locking regimes with opposite sign
