“…However, the specific impact of adding an SMF to a Brillouin fiber laser depends on factors like the SMF's properties, laser cavity design, and intended application [22]. Careful consideration and optimization are necessary to achieve the desired performance enhancements or modifications [23].…”

Using erbium-doped fiber, a steady Q-switched erbium-doped laser (EDFL) was successfully demonstrated. With a 150 m of Single Mode Fiber to generate the Brillouin Fiber Laser and increase the non-linearity inside the cavity. In the absence of a Brillouin pump, a compact Brillouin fiber laser (BFL) is realized by combining an Erbium Doped Fiber (EDF) and a Single Mode Fiber (SMF), which serve as both the Brillouin and linear gain media. It is accomplished by self-Brillouin production in a laser cavity from 4.5 m of EDF and 150 m of SMF with strong nonlinearity. The SMF inside the ring cavity was used to generate self-generating BFL. The BFL in the linear cavity produced more Brillouin stokes at a lower pump threshold. In the experiments, the average of spacing is 0.088 nm was generated at the EDF pump power of 93.468 to 259.493 mW for the 150 m of SMF. This compact BFL has total cavity length (160.34 m). Eventually, this is the most recent gain medium length recorded for Brillouin erbium fiber laser production without the use of a Brillouin pump.

“…The new fiber grating concept of two-dimensional fiber grating studied in this subject is based on the multi-wavelength filter structure in the wavelength division multiplexing system [11][12][13] and the resonator structure of the multi-wavelength laser [14][15][16][17]. The refractive index is one-dimensionally modulated, and two-dimensional fiber grating refers to fiber gratings with multiple different periods distributed on the sub-wavelength scale of the fiber core, in order to realize a new structure of compact gratings with multi-channel and multi-wavelength output.…”

In this paper, the preparation and spectral properties of large mode field double-clad (LMA) fiber two-dimensional fiber gratings are studied. Firstly, a new compact grating analysis model for writing fiber gratings with different periods in different regions of the fiber core is theoretically proposed, and the spectral characteristics of the gratings written in different regions of the fiber core are studied based on the transfer matrix method. A three-wavelength two-dimensional fiber grating with a designed wavelength interval of 1.57 nm was successfully fabricated using a 248 nm excimer laser in a large mode field double-clad fiber laser. The research results show that the spectral characteristics of the two-dimensional fiber grating can be changed flexibly by changing the masking parameters, and the structure is compact. The experimentally obtained two-dimensional fiber grating spectrum is consistent with the theoretical analysis. The research results provide a theoretical reference for the design, fabrication and application of two-dimensional fiber gratings.
