Abstract

This is a proposal to develop a high power, single mode, low noise and narrow linewidth fiber laser based on a virtual ring laser cavity. This novel laser architecture enables traveling-wave oscillation in a compact, linear and all-fiber cavity. The traveling-wave laser field eliminates spatial hole burning, a feat usually achieved only in a ring laser. This significantly improves the laser power, the signal-to-noise ratio, linewidth and the side mode suppression to unprecedented levels.
