“…Fabrication of rare earth (RE 3+ )-doped optical fibers is typically performed by solution doping [2] where salts of the rare earth ion, such as ErCl 3 and Al (added to decrease clustering of the REs) are dissolved in a solvent and introduced into a layer of porous silica "soot" that is subsequently dried and consolidated to form the fiber core. However, there is no mechanism for controlling the molecular environment about the RE 3+ ions when solution doped into the homogeneous glass.…”

Abstract:A nanoparticle (NP) doping technique was developed for fabricating erbium (Er)-and holmium (Ho)-doped silica-based optical fibers for high energy lasers. Slope efficiencies in excess of 74% were realized for Er NP doping in a single mode fiber based master oscillator power amplifier (MOPA) and 53% with multi-Watt-level output in a resonantly cladding-pumped power oscillator laser configuration based on a double-clad fiber. Cores comprising Ho doped LaF 3 and Lu 2 O 3 nanoparticles exhibited slope efficiencies as high as 85% at 2.09 µm in a laser configuration. To the best of the authors' knowledge, this is the first report of a holmium nanoparticle doped fiber laser as well as the highest efficiency and power output reported from an erbium nanoparticle doped fiber laser.

“…Yb/Tm co-doped yttrium-alumino-silicate (YAS) fibers were fabricated by modified chemical vapor deposition (MCVD) process in conjunction with solution doping (SD) technique. Since 1987, SD technique has been used to incorporate rare-earths [12] and nanoparticles [10,[13][14][15][16] into the silica glass matrix of optical fibers.…”

Abstract:We report the results of experimental investigation and theoretical analysis of luminescence decay in Yb/Tm Y-codoped fibers based on nano-modified glass. Based on the experimental results, numerical simulations allowed us to estimate the energy transfer efficiency between Yb 3+ and Tm 3+ ions. It was shown that yttria enhances the Yb/Tm energy transfer making fibers with Y-codoping promising for development of the light sources for laser applications and of up-conversion emitters for visualization applications. These fibers demonstrate energy transfer efficiency of 50 %, which makes them attractive for diode-pumping of Ybions at 975 nm wavelength.

“…Moreover, core refractive index is required to be the same as that of the cladding in most of these designs such as PCF, LCF, Re-LCF, 2D-ASPBGF, Bragg fiber, MTF, and PTF and this requires microstructuration or pixelation of doped core in order to match the refractive index with undoped cladding, which is a cumbersome process to do. On the other hand, SIF can be fabricated with conventional technique, such as Modified Chemical Vapor Deposition Process (MCVD) in conjunction with solution doping process [16][17][18] and suitable for mass production. Ming-Jun Li et al demonstrated that the maximum scalable mode area for effective single mode operation from a SIF is 370µm 2 for 1060nm operation taking into account the core numerical aperture (NA) to be 0.06 that could be achieved experimentally at the time of publishing the paper in 2009 [19].…”

Abstract:In this paper, we report the mode area scaling of a rare-earth doped step index fiber by using low numerical aperture. Numerical simulations show the possibility of achieving an effective area of ~700um 2 (including bend induced effective area reduction) at a bend diameter of 32cm from a 35μm core fiber with a numerical aperture of 0.038. An effective single mode operation is ensured following the criterion of the fundamental mode loss to be lower than 0.1dB/m while ensuring the higher order modes loss to be higher than 10dB/m at a wavelength of 1060nm. Our optimized modified chemical vapor deposition process in conjunction with solution doping process allows fabrication of an Yb-doped step index fiber having an ultra-low numerical aperture of ~0.038. Experimental results confirm a Gaussian output beam from a 35μm core fiber validating our simulation results. Fiber shows an excellent laser efficiency of ~81% and a M 2 less than 1.1. 2015 Optical Society of AmericaOCIS codes: (060.2280) Fiber design and manufacturing; (140.3510) Fiber lasers.
