Comparative analysis of the DFB fiber laser and fiber-optic interferometric strain sensors [PDF]
, 2007 The DFB fiber laser strain sensor is shown to provide an improvement in the minimum detectable length change by a factor of 275 at 2 kHz for an applied strain when compared with an interferometric sensor interrogated by at equivalent DFB laser.

Narrow–linewidth tunable laser source for long-wavelength optical coherence tomography at 1700 nm [PDF]
EPJ Web of ConferencesWe present a widely tunable laser source with narrowed linewidths at the level of 0.4 – 1.1 nm. The laser source incorporates a comb-profile fiber (CPF) which allows for spectral compression of the tunable optical pulses to the linewidths below 1 nm. The

Mode-Locking Dynamics in an All-PM Figure-Nine Tm-Doped Fiber Laser
Applied Sciences, 2022 We report a study on pulse dynamics in figure-nine Tm-doped all-polarization maintaining fiber laser. We analyzed laser operation from self-starting with multi-pulse dynamic to single-pulse operation by decreasing the pump power from the mode-locking ...

Dysprosium-doped ZBLAN fiber laser tunable from 2.8 μm to 3.4 μm, pumped at 1.7 μm. [PDF]
Optics Letters, 2018 We demonstrate a mid-infrared dysprosium-doped fluoride fiber laser with a continuously tunable output range of 573 nm, pumped by a 1.7 μm Raman fiber laser. To the best of our knowledge, this represents the largest tuning range achieved to date from any
