Fiber Lasers and Their Coherent Beam Combination
With high efficiency and exceptional beam quality, fiber lasers hold great promise. The 1-µm wavelength makes it possible for them to replace both diode- and lamp-pumped Nd:YAG lasers in the micromachining, automotive and biomedical markets.

Fiber lasers with up to kW-level output power are now technologically sophisticated, and fiber-based laser systems for industrial applications have hit the market. These lasers are being developed not only for continuous-wave and long-pulsed-mode operation but also in the picosecond pulse mode.
