Abstract

A holmium non-linear polarisation rotation (NLPR) all-fibre mode-locked laser was characterised. The radiofrequency (RF) spectrum of the pulsed train output was used as an automation metric. Non-ideal pulsing behaviour was corrected by changing the intracavity polarisation state using actuators in an electronic polarisation controller. The optimum cavity produced mode-locked pulses with a central wavelength of 2.061 μm and an 8.7 nm optical full-width-at-half-maximum (FWHM).
