TL;DR: In this paper, a source of pulses of coherent radiation at a wavelength of approximately 1 μm, consisting of a pump source for producing pump light, a laser cavity comprising an Yb3+-doped gain medium arranged to receive the pump light and at least one optical amplifier for amplifying the laser pulses of reduced repetition rate, can be configured for chirped or parabolic pulse amplification.

TL;DR: Active pulse shaping using an Electro-Optic Modulator is demonstrated in order to compensate the pulse shaping effects caused by Gain Saturation in a high power Yb doped fiber amplifier chain and to generate various custom-defined output pulse shapes.

TL;DR: It is reported that picosecond fiber MOPA pumped supercontinuum source with 39W output, spanning at least 0.4–1.75µm with high and relatively uniform spectral power density, corresponding to peak power density of ∼12.5W/nm in 20ps pulse.

TL;DR: This paper demonstrates a single polarisation, 1.06 microm Yb-doped fiber MOPA, delivering 21 ps pulses in a diffraction limited beam at repetition rates of up to 908 MHz and average output power of 100 W, limited by available diode pump power.

TL;DR: The rapid development of commercial multi-kW continuous-wave fibre lasers and high-peak power fibre lasers leads to a natural convergence toward high-average power high- peak power pulsed fibre lasers whose applications include marking, trimming, micromachining, precision drilling, welding and cutting while retaining the characteristics advantage of the fibre laser.
