Combining laser beams to gain power
One of the architectures implemented for the construction of a high-power fiber laser is the possibility of combining different laser beams. Knowing that today a single fiber laser can deliver a power of the order of a kilowatt, or even ten kilowatts, the optical combination by phasing multiple sources results in a new laser delivering powers of up to several hundred kilowatts. There are several techniques for combining lasers. Among them, two require the use of phase modulators: the spectral combination of laser beams and the coherent combination of beams. For each of these architectures, iXblue has managed to develop a dedicated product (bandwidth, driving voltage, suppression of non-linear effects, etc…).
