L-Band Erbium Fiber Laser with Tunable and Narrow Sub-kHz Linewidth Output

L-Band Erbium Fiber Laser with Tunable and Narrow Sub-kHz Linewidth Output

In this paper, a wavelength-selectable erbium-doped fiber (EDF) laser in L-band bandwidth with a simple structure and low cost is described. To obtain stable single-longitudinal-mode (SLM) and narrow laser linewidth, the 2 m unpumped EDF-based saturable absorber (SA) and 100 m single-mode fiber (SMF...
