Abstract:
1. A laser system for decreasing a coherence length of a tunable laser, the laser system comprising: the tunable laser; one or more tuning elements adapted to modulate at least one parameter associated with the tunable laser over a period of time; the parameter controlling an output wavelength of the tunable laser, wherein the parameter is modulated such that a linewidth of the tunable laser increases and a point spread function measured through a fiber optic component changes; and the fiber optic component adapted to receive electromagnetic radiation output by the tunable laser, the fiber optic component comprising at least one spurious etalon; wherein the parameter is modulated such that the output wavelength of the tunable laser changes by an amount larger than a free spectral range of the spurious etalon over an interval of time shorter than a measure time of the laser system.
