Laser peak power scaling and beam quality improvement …
At present, the combination of high peak power and near diffraction-limited beam quality is essential for high-power pulsed fiber laser systems combining nanosecond pulses with multi-kilohertz repetition rates. In standard fiber amplifier, parasitic nonlinear effects limit further power scaling due to the small active fiber core. Therefore the scaling to larger …

Rod-type fiber laser reaches new nanosecond pulse-power heights
Engineers and scientists at Femlight (Talence, France) and the University of Jena (Jena, Germany) have created a rod-type fiber laser with a very large core and short length that overcomes the limits of conventional fiber lasers and diode-pumped solid-state (DPSS) rod lasers for short-pulse generation.
