Fiber Lasers, Tunable, Thulium


Fabry-Perot based filters have long been an attractive interferometric device due to its simple construction and versatility for various applications. In this paper, we demonstrate a bidirectional-pumped tunable Thulium-doped Fiber Laser (TDFL) using a voltage-controlled Fabry-Perot Etalon (FPE) filter. The filter allows a maximum tuning range of ~42.0 nm, from 1965.40 nm, up to 2007.35 nm. The generated laser also exhibits a relatively low threshold power of ~62.57 mW and narrow bandwidth of ~0.16 nm. The tuning capability exhibits an exponential growth relationship which can be exploited for precise automatic electronic control.
