Abstract
Until recently, the output power of single-mode fiber amplifiers and lasers has been limited by the pump power available from single stripe laser diodes and the limited means of power scaling through multiple diode laser pumping. The recent demonstration of fiber lasers that function as diode laser array brightness converters (cladding-pumped fiber lasers) and diffraction-limited high-power diode lasers (MOPAs) has now allowed pump powers of several watts to be obtained from a single-mode fiber core. This has led to the demonstration of high-power 1.5-μm and 1.3-μm fiber amplifiers and highpower 1.48-pm fiber lasers. The availability of these highpower pump sources has enabled larger passive split fiber architectures, long-distance repeaterless spans, and new nonlinear fiber devices.
