Malinowski, Andrew; Vu, Khu Tri; Chen, Kang Kang; Nilsson, Johan; Jeong, Yoonchan; Alam, Shaiful; Lin, Dejiao; Richardson, David J


We demonstrate active pulse shaping using an Electro-Optic Modulator 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. Square, step and smooth pulse shapes are achieved, with mJ pulse energies. Use of a modulator to shape pulses rather than direct modulation of the diode drive current allows us to eliminate undesired transients due to laser start up dynamics. The...[Show more]
