We present an experimental characterization of a fiber laser composed by an Yb-doped fiber spliced with a birrefringent photonic crystal fiber and a mechanically-induced long-period grating (LPG) into the laser cavity. According to the torsion properties of the LPG induced in the photonic crystal fiber, the Yb-doped fiber laser can be highly sensitive to twist and it can shown novel properties in its laser emission. Also, we show the splitting of attenuation bands of a longperiod fiber grating induced mechanically in different twisted photonic crystal fibers with high birefringence and their applications on the performance of tunable and switchable multiwavelength double-clad Ytterbium-doped fiber lasers.
