Abstract

A skew-angle cladding-pumped tunable Yb-doped fiber laser is presented. The laser was tunable over more than $30\mathrm{nm}$, from 1022 to $1055\mathrm{nm}$, by employing a volume Bragg grating in a retroreflector configuration as one of the cavity delimiters. Output powers in excess of $4.3\mathrm{W}$ were recorded with a spectral bandwidth of $5\mathrm{GHz}$ and an $M^2$ value below 1.3 over the whole tuning range.
