High power double-clad Yb-doped fiber laser

摘要

We present an experimental study of the Yb-doped double-clad fiber laser operating in the 1.08 μm wavelength. The fiber is side-pumped with a high power laser diode using the v-groove technique. Various experimental configurations are performed from the linear cavity to an all-fiber tunable unidirectional ring cavity. Mode-locking properties of the Yb laser are investigated using the nonlinear polarization rotation.
