Abstract

A large Nd-doped core placed in a microstructure cladding (holey fiber) was pumped with a low-brightness diode laser. The area ratio of the pump radiation on the fiber to the core was larger than 30. The fiber length was 38 cm. Butt coupled mirrors formed the laser cavity. The emitted radiation at λ = 1060 nm was single transverse mode, the output power amounted to about 10 mW.
