Abstract

A moderate output power Yb3+-doped double-clad fibre laser pumped by an unfocused diode laser is reported. This pumping configuration omits micro positioned lenses used in fibre coupled laser diodes, thus making the system significantly less complex and more robust. The maximum launch efficiency was ∼80% and the maximum output power was >5 W with a measured FWHM of 18 pm.
