“…The first single-frequency phosphate fiber laser emitting at 1.5 µm was reported in 2003 [77], with an output power of 100 mW and a very narrow linewidth of less than 2 kHz. It was a DBR fiber laser based on an heavily Yb 3+ /Er 3+ co-doped fiber (3 wt % of Yb 3+ and 2 wt % of Er 3+ ) that displays very high optical gain per unit length of up to 5 dB/cm.…”

Abstract:In recent years, the exploitation of compact laser sources and amplifiers in fiber form has found extensive applications in industrial and scientific fields. The fiber format offers compactness, high beam quality through single-mode regime and excellent heat dissipation, thus leading to high laser reliability and long-term stability. The realization of devices based on this technology requires an active medium with high optical gain over a short length to increase efficiency while mitigating nonlinear optical effects. Multicomponent phosphate glasses meet these requirements thanks to the high solubility of rare-earth ions in their glass matrix, alongside with high emission cross-sections, chemical stability and high optical damage threshold. In this paper, we review recent advances in the field thanks to the combination of highly-doped phosphate glasses and innovative fiber drawing techniques. We also present the main performance achievements and outlook both in continuous wave (CW) and pulsed mode regimes.Keywords: fiber laser and amplifier; phosphate fiber; all-fiber master oscillator power amplifier (MOPA); rare-earth-doped fiber

“…The line fiber laser can generate a highpower laser. Using an Er 3+ /Yb 3+ co-doped phosphosilicate fiber with relatively high doping concentrations, distributed Bragg reflector (DBR) lasers showed output powers of up to 100 mW and a very narrow linewidth of less than 2 kHz [12,13]. A 200 mW, narrow linewidth 1064.2 nm Yb 3+ -doped fiber laser has also been reported using the same short fiber grating F-P cavity [14].…”

A high Er 3+ -doped narrow linewidth fiber laser based on fiber Bragg grating Fabry-Perot cavity was demonstrated. The spatial hole burning effect was restrained by a fiber Faraday rotator. Two short fiber Bragg grating Fabry-Perot cavities as narrow bandwidth filters discriminated and selected laser longitudinal modes efficiently. A stable single-frequency 1534.83 nm laser was acquired. Pumped by two 976 nm laser diodes and twoended output, the fiber laser exhibited a 12 mW threshold. Total 39.5 mW output power and one end 22 mW output power were obtained at the maximum 145 mW pump power. Optical-optical efficiency was 27% and slope efficiency was 29.7%. The output power seemed to be saturated when pump power increased. The 3 dB linewidth of the laser was less than 7.5 kHz, measured by the delayed self-heterodyne method with 15 km monomode fiber. The high power narrow linewidth fiber laser can be used in high resolution fiber sensor systems.

“…In the past two decades, The linear cavity with distribute Bragg reflective (DBR) structure made of fiber Bragg gratings (FBGs) was used to obtain stable single frequency output in the field of fiber laser [9][10][11][12][13][14][15][16]. There are two reflective peaks sepa rated by the wavelength and polarization orthogonal when the FBG is imprinted in the polarization main taining fiber (PM FBG).…”

“…Including one of the two reflective peaks of the PM FBG in the reflective peak of another reflective mirror of the laser cavity would result to only one polarization eigenmode resonant in the laser cavity. Generally, the output laser is single polarized for current DBR structures [12][13][14]. In [12], the polarization extinction ratio (PER) of the single polarization output laser is greater than 20 dB.…”

Abstract-The polarization properties of a distribute Bragg reflective (DBR) all fiber laser configured with a common single mode high reflectivity fiber Bragg grating (SM FBG) and a polarization maintaining fiber Bragg grating (PM FBG) are analyzed theoretically and investigated experimentally. Matching the reflective peak of SM FBG with one of the PM FBG reflective peaks in an ideal active fiber (without birefringence) would yield a linear polarization light. However, the polarization properties of a fiber laser become very com plex when a birefringence is induced into the active fiber. Different polarization properties (linear polariza tion, elliptical polarization, or circular polarization) of the fiber laser appear with the variation of the bire fringence. Two perpendicular axes in the active fiber induced by the birefringence effect must be matched with that of PMFBG to realize the linear polarization output.
