Highest peak power and excellent stability demonstrated in a laser

Power-scalable ultrafast laser sources in the midwave-infrared (MWIR) are a key element for basic research and applications in material processing and medicine. Optical amplifiers based on chirped pulse amplification (CPA) are used to generate high intensity pulses, a technique awarded with the Nobel Prize in physics in 2018. In the CPA scheme, a weak temporally stretched seed pulse is amplified to high energy in a laser amplifier and finally re-compressed resulting in an ultrashort pulse of ver...
