PROJECT TITLE :

Stable Gain-Switched Thulium Fiber Laser With 140-nm Tuning Range

ABSTRACT:

We demonstrate a gain-switched thulium fiber laser which will be continuously tuned over one hundred forty nm, whereas maintaining stable nanosecond single-pulse operation. To the simplest of our data, this technique represents the broadest tuning range for a gain-switched fiber laser. The system simplicity and wideband wavelength tunability combined with the ability to regulate the temporal characteristics of the gain-switched pulses mean this is often a flexible source highly suited to a wide range of applications in the eye-safe region of the infrared, together with spectroscopy, sensing and material processing, also being a sensible seed supply for pumping nonlinear processes.
