Introduction to the issue on high-power fiber lasers ...- introduction to high power fiber lasers ,Introduction to the issue on high-power fiber lasers. The 26 papers in this special issue focus on high-power fiber lasers. The papers can be grouped into three comparatively narrow categories: waveguide engineering and propagation; pulsed fiber lasers and amplifiers; and novel laser schematics, wavelengths, and materials. Fiber Laser - High-power Fiber LaserThe laser reaches an output power of 2.4 kW from a single fiber laser module, with a nominal power of 2 kW. Up to four fiber laser units can be combined by an all-fiber power combiner for a total nominal power of 8 kW, which can be delivered by up to four 100-μm-core-diameter process fibers to the processing cell.
The introduction of high-power fiber, disk lasers is beginning to challenge traditional CO 2 lasers for cutting and welding. There are, however, many challenges. For example, focus shift has been found to be one of the main problems for fiber lasers.
Editor' Comments. This book provides a comprehensive review of current high-power fiber laser (HPFL) technology. It is intended as an introduction to this rapidly developing field but can also be used by researchers and technology managers as a handy and comprehensive reference. It contains a broad review ranging from a history of HPFLs to an introduction of the science and engineering required for full HPFL systems, plus the authors' predictions of future applications and research directions.
Due to the introduction of large mode area (LMA) fibers as well as continuing advances in high power and high brightness diodes, continuous-wave single-transverse-mode powers from Yb-doped fiber lasers have increased from 100 W in 2001 to over 20 kW.

A high-power fiber laser collimator and array of collimators are described with optical architecture, allowing one to transmit almost of the full power output from fiber facets. In the case of coherent beam combining, more than 70% of the full power can be focused into a diffraction limited spot determined by the diameter of the conformal ...
Compared with other types of lasers, solid-state lasers possess the advantages of flexible design, high output power density, excellent wavelength expansibility, and strong power scaling ability. Since its first invention in 1960, the solid-state laser has been playing an important role in the fields of directional energy, industrial manufacturing, high-intensity physics, and cutting-edge ...

This differentiates the fiber laser to other types of laser available on the market, where the active laser medium is a crystal (e.g. disk laser) or gas (e.g. CO 2 laser). Fiber lasers provide absolute efficiency, precisely control speed and power through accurate management of the beam length, duration, intensity, and heat output.

Beginning with a introduction to the current state of the art in fiber lasers, the authors follow with a detailed, technical overview of HPFLs, first providing an introduction to optical waveguides in silica glass fibers and then a technical review of fiber amplifiers and lasers. A chapter is also included on fiber laser limitations. To circumvent the current limitation on single-fiber laser output power, chapters are provided on beam combining, beam quality, and Fourier optics to further ...
Typical optical-to-optical power efficiencies are above 50%, sometimes even above 80%; the overall electrical-to-optical power conversion efficiency of a diode-pumped fiber laser can be of the order of 50% for an Yb-based fiber laser pumped with efficient high-power diode lasers.
