“…By employing the chemical etching together with the polymers recoating technique [181], Poozesh et al reported a CPS with the hundred-watt stripping ability. Since then, targeted 100-watt stripping for CPS has achieved great progress [151,[176][177][178][179][180][181][182][183][184]. The traditional CPS generally removes the cladding light in a short length of fiber, which may result in high local temperature under a cladding light power of 1 kW, thus disrupting the stable operation of the laser source.…”

The success of high-power fiber lasers is fueled by maturation of active and passive fibers, combined with the availability of high-power fiber-based components. In this contribution, we first overview the enormous potential of rare-earth doped fibers in spectral coverage and recent developments of key fiber-based components employed in high-power laser systems. Subsequently, the emerging functional active and passive fibers in recent years, which exhibit tremendous advantages in balancing or mitigating parasitic nonlinearities hindering high-power transmission, are outlined from the perspectives of geometric and material engineering. Finally, novel functional applications of conventional fiber-based components for nonlinear suppression or spatial mode selection, and correspondingly, the high-power progress of function fiber-based components in power handling are introduced, which suggest more flexible controllability on high-power laser operations.

“…All these methods have their advantages and disadvantages as follows: (i) Working with HF and acidic fluorides requires a great deal of attention, but this method appears to be successful at attenuating 27 dB of the pumped light with the NA of 0.44 [1]. Furthermore, the etched fiber can be tapered despite the fact that the term "tapering" is generally used upon applying the heat-pull method but can also be referred to for acidic tapering [9]. In acidic tapering, only the cladding is tapered; thus, the signal light is not perturbed as compared to the heat-pull method.…”

“…Many groups have demonstrated CLSs fabricated by coating and/or etching methods. These include [5] the high-index polymer with 18 dB loss [4], the soft metal coating with 20 dB loss [10], an interesting study on high-power CLS preparation with 20 dB using recoating fiber surface with a capillary glass [8], and chemical etching methods with 27 dB and 16.7 dB loss [1,7,9]. However, no detailed studies on the precise information about the optimum etching conditions and utilizing different chemical etching methods, including chemical stain etching and vapor-phase etching were reported on the performance of CLSs.…”

Combined method for the fabrication of high-power cladding light stripper using a buffered oxide etchant

et al. 2019

Cladding light strippers (CLSs) are vital and one of the critical components for high-power fiber laser applications. In this study, we show the first studies of the formation mechanisms and optimum conditions of a CLS device using a buffered oxide etchant by a combined method of stain (wet) etching and vapor-phase etching. This highpower CLS was shown to result in a stripping performance of ∼17.2 dB at the launched power of 333 W (pump limited). The thermal imaging demonstrates that the maximum temperature reached when operating the device at maximum launched power was ∼75°C. The atomic force microscopy (AFM) results show that the combined method yields crystal-like structures with the height in microscales, whereas other conventional methods give only nanoscale roughness. The method also preserves the diameter of the CLS device close to the bare fiber with about 10 μm tapering leads to a high surface area to strip unwanted light, which is good for heat dissipation. The combined method possesses the outcome of two methods, including both the crystal-like structures and nanosized hillocks, resulting in high-power stripping performance and robustness.
