Route to OCT from OFS at University of Kent

In this paper, we reported the realization of an ultra-long ring fiber laser (RFL) with hybrid emission related to both random lasing and cavity resonance. Compared with a linear random fiber laser (LRFL), the Rayleigh scattering (RS) inducting distributed feedback effect and the cavity inducting resonance effect exist simultaneously in the laser, which reduces the lasing threshold considerably and provides a hybrid way to form random lasing (RL). The laser output can be purely modeless RL when pump power is high enough. It is also discovered that the laser is insensitive to temperature variation and mechanical disturbance, this is unique and quite different from conventional RFLs which are environmentally unstable due to existence of the cavity modes.

Route to OCT from OFS at University of Kent

Abstract: A review is presented of several technical solutions developed by the Applied Optics Group (AOG) in the field of low coherence interferometry applied to optical fiber sensors (OFS) that subsequently allowed AOG to quickly progress in the field of optical coherence tomography (OCT).
