Continuous electronic tuning of a narrowhyphen;band Nd3+hyphen;fiber laser

摘要

Continuous electronic tuning of a linear Nd3+hyphen;fiber laser near 1088 nm wavelength is demonstrated by controlling the relative phase of two cascaded intracavity frequency shifters. A servoloop tracks the mode selecting elements of the laser with respect to the oscillation frequency and permits complete suppression of mode jumps.
