Cladding-pumped fiber laser

Laser emission at 1.06 /spl mu/m, pump light absorption, laser threshold, slope efficiency, and alignment tolerance as a function of the fiber length have been measured for a cladding-pumped double-clad Nd:glass fiber laser. The fiber laser was pumped with a laser diode emitting at 810 nm. It produced an output power of 15.9 mW at an absorbed pump power of 55.1 mW. This corresponds to an optical-optical conversion efficiency of 38.8%.<
