Abstract

In the era of high-power laser systems, there is a constant demand for compact and efficient short-pulsed amplifiers delivering high power with an excellent beam profile and high polarization stability. In this presentation, I will review the advantages of active tapered double-clad fiber amplifier technology and different geometrical concepts. The special geometrical architecture of tapered fibers enables the direct amplification of picosecond pulses from tens of milliwatts to hundreds of watt levels in a single amplification stage. The recent technological progress in tapered fibers led to a doubling of the average power level, preserving excellent output spatial and polarization characteristics. The spun tapered fiber features low birefringence resulting in improved polarization stability at high power levels. Moreover, this geometrical architecture is exploited for the amplification of structured light, maintaining complex polarization profiles and spatial intensity distribution.
