Single-frequency fiber oscillator with watt-level output power using photonic crystal phosphate glass fiber

Opt Express. 2006 Aug 7;14(16):7087-92. doi: 10.1364/oe.14.007087.

Abstract

Utilizing phosphate glass fiber with photonic crystal cladding and highly doped, large area core a cladding-pumped, single-frequency fiber oscillator is demonstrated. The fiber oscillator contains only 3.8 cm of active fiber in a linear cavity and operates in the 1.5 micron region. Spectrally broad, multimode pump light from semiconductor laser diodes is converted into a single-mode, single-frequency light beam with an efficiency of about 12% and the oscillator output power reached 2.3 W.
