Abstract：We demonstrate the generation of passive mode-locked double-clad ytterbium-doped fiber laser operating in a 1-micron region. We prepare the saturable absorber from commercial crystal of molybdenum disulphide (MoS$_{2}$). Without chemical procedure, the MoS$_{2}$ is mechanically exfoliated by using a clear scotch tape. A few layers of MoS$_{2}$ flakes are obtained on the tape. Then, a piece of $1\times1$ mm tape containing MoS$_{2}$ thin flakes is inserted between two fiber ferrules and is integrated in the ring cavity. Stable mode-locking operation is attained at 1090 nm with a repetition rate of 13.2 MHz. Our mode-locked laser has a maximum output power of 20 mW with 1.48 nJ pulse energy. These results validate that the MoS$_{2}$ has a broad operating wavelength which covers the 1-micron region, and it is also able to work in a high-power cavity.
