“…Note that the proposed TDFL performs as a switchable multi-wavelength laser. However, the wavelength of the output laser could be tunable if a wavelength tuning mechanism is employed, such as a stress regulator [25], curvature adjuster [26], displacement platform [27], and solutions with different refractive indices [28], and thus a wavelength-switchable and tunable TDFL can be obtained.…”

A continuous wave, switchable multi-wavelength, thulium-doped fiber laser (TDFL) with a polarization-maintaining sampled fiber Bragg grating (PM-SFBG) is proposed and demonstrated for the first time. A length of 150 m highly-nonlinear fiber (HNLF) was used to introduce the four-wave mixing effect for the efficient suppression of the wavelength competition existing in the gain medium of thulium-doped fiber. By adjusting the state of polarization (SOP) of light in the laser cavity, two six-wavelength operations at two orthogonal SOPs and a ten-wavelength operation were obtained. When the TDFL ran at the six-wavelength operation mode with a pump power of 4.11 W, there were at least four lasing wavelengths with an optical signal-to-noise ratio (OSNR) higher than 30 dB, and when it ran at the ten-wavelength operation mode with a pump power of 4.60 W, there were nine lasing wavelengths with an OSNR higher than 30 dB. Regardless of the operation mode, the TDFL exhibited high stability.INDEX TERMS Multi-wavelength, sampled fiber Bragg grating, thulium-doped fiber laser.

“…Moreover, by controlling the stress applied on the NB-FBG, an interval of tunable dual-wavelength from 0.430-4.847 nm is achieved [17]. In 2018, Ibarra-Escamilla et al reported a tunable dual-wavelength operation of an all-fiber thuliumdoped fiber laser based on tunable FBG, where an interval of tunable dual wavelength from 0.54-9.00 nm is obtained [18]. In 2020, Gao et al reported a dual-wavelength tunable ringcavity fiber laser based on FBG and an externally injected distributed feedback (DFB) laser.…”

A switchable and tunable erbium-doped fiber laser with a linear cavity based on fiber Bragg gratings embedded in Sagnac rings is proposed and experimentally verified. Due to the stress birefringence effect and the polarized hole burning effect, which are introduced into the single-mode fiber in the polarization controllers (PCs) by the PCs, the designed laser can achieve seven kinds of laser-states output including three kinds of single-wavelength laser states, three kinds of dual-wavelength laser states and one kind of triple-wavelength laser state. The optical signal-to-noise ratios of the output wavelengths are all higher than 52 dB, and the wavelength shifts are all less than 0.04 nm. Furthermore, the temperature tuning of the wavelength range is also researched, which is about 1.2 nm. Due to advantages, such as low cost, simple structure, easy switching and multiple laser states, the designed laser has great application potential in laser radar, optical fiber sensing and so on.

“…Moreover, fiber-based interferometers have been widely studied due to their many applications in areas such as optical sensing, photonic components characterization, wavelength-division multiplexing (WDM), spectroscopy, and optical metrology, etc. [21][22][23]. In this sense, an important application of fiber interferometers lies in its use as a spectral filter for wavelength selection and tuning of generated laser lines in fiber laser configurations; for optical systems that require coherent light emission, tunable over a specific wavelength range.…”

TiOxNy Thin Film Sputtered on a Fiber Ball Lens as Saturable Absorber for Passive Q-Switched Generation of a Single-Tunable/Dual-Wavelength Er-Yb Double Clad Fiber Laser

et al. 2020

The use of titanium oxynitride (TiOxNy) thin films as a saturable absorber (SA) element for generation of passive Q-switched (PQS) laser pulses, from a linear cavity Er-Yb double-clad fiber (EYDCF) laser, is demonstrated. Additionally, the deposition of the material as a thin film covering a fiber micro-ball lens (MBL) structure is reported for the first time. The TiOxNy coating is deposited by a direct current (DC) magnetron-sputtering technique. The MBL is inserted within the laser cavity in a reflection configuration, alongside a reflecting mirror. As a result, the coated fiber MBL simultaneously acts as a SA element for PQS laser pulses generation and as an interference filter for wavelength selection and tuning of the generated laser line. Tunable single-laser emission in a wavelength range limited by dual-wavelength laser generation at 1541.96 and 1547.04 nm is obtained. PQS laser pulses with a repetition rate from 18.67 to 124.04 kHz, minimum pulse duration of 3.57 µs, maximum peak power of 0.359 W, and pulse energy of 1.28 µJ were obtained in a pump power range from 1 to 1.712 W.
