Abstract

We report on an intracavity configuration for supercontinuum generation in a Q-switched Yb fiber laser. The supercontinuum laser includes a section of microstructured fiber within the Q-switched laser cavity. With $380\mathrm{mW}$ of pump power, the supercontinuum laser can emit broadband pulses of $6\mu \mathrm{J}$ energy and $10\mathrm{ns}$ temporal width, at repetition rates from few hertz up to $2\mathrm{kHz}$. The supercontinuum spectrum spans over a wavelength range in excess of $1.4\mu \mathrm{m}$.
