“…Lasers in the 2-μm band are particularly important because they operate in the atmospheric transmission window and in the human eye safety band. Various thulium-doped fiber lasers (TDFLs) such as Q-switched TDFL [1], mode-locked TDFL [2], [3], multi-wavelength TDFL [4]- [7], and narrow linewidth TDFL [8]- [10] are currently available, and, among these, the multi-wavelength TDFL has attracted intense research attention in recent years, since the multi-wavelength fiber lasers have the great potential in a wide range of applications, for instance, gas spectroscopy [11], fiber sensing [12], wavelength division multiplexing systems [13], and photonic generation of microwave signals [14].…”

A switchable multi-wavelength thulium-doped fiber laser (TDFL) using a fourmode fiber based Sagnac loop filter was proposed and demonstrated. The Sagnac loop, incorporating a 4.8 m long four-mode step-index fiber, acting as a comb filter was analyzed theoretically and experimentally. By adjusting two polarization controllers, eight stable single-wavelength operations and five stable dual-wavelength operations were obtained with easy switching between the different operation modes. The wavelength range covered during the single-wavelength switchable operation with a signal-to-noise ratio of up to 55 dB was ∼28.51 nm. In dual-wavelength switchable operation, the maximum and minimum wavelength spacings were ∼21.78 nm and ∼1.50 nm, respectively. Due to the abundant wavelength resources, the proposed TDFL has great potential in wavelength division multiplexing free-space optical communications, optical fiber sensing, and photonic generation of microwave signals.

In this work, we have demonstrated tunable 1.8-µm laser operation based on a Tm:YVO4 cladding waveguide fabricated by means of femtosecond laser direct writing. Benefiting from the good optical confinement of the fabricated waveguide, efficient thulium laser operation, with a maximum slope efficiency of 36%, a minimum lasing threshold of 176.8 mW, and a tunable output wavelength from 1804 to 1830nm, has been achieved in a compact package via adjusting and optimizing the pump and resonant conditions of the waveguide laser design. The lasing performance using output couplers with different reflectivity has been well studied in detail. In particular, due to the good optical confinement and relatively high optical gain of the waveguide design, efficient lasing can be obtained even without using any cavity mirrors, thereby opening up new possibilities for compact and integrated mid-infrared laser sources.
