Abstract: A broadband light source (e.g., an optical supercontinuum apparatus), can comprise a pump laser; a non-linear optical element configured for generating spectrally broadened light generated responsive to receiving pump laser pulses and one or more non-linear processes; an optical output for delivering spectrally broadened light to a target; a length of optical waveguide optically upstream of the output and in optical communication therewith; and a sensor apparatus. The length of optical waveguide can comprise at least a first waveguiding region configured for propagating spectrally broadened light in a forward direction toward the output and can be further configured for receiving backward propagating light responsive to the forward propagating light. The sensor apparatus can be configured for optical communication with the length of optical waveguide so as to sense the backward propagating light propagated by the length of optical waveguide. Methods for operating and using such broadband light source are disclosed, as are applications of the methods and apparatus.
