WebOct 19, 2024 · By balancing the gain-narrowing effect with self-phase modulation during the amplification, we achieved an average output power of 11 W, corresponding to a pulse energy of more than 1 µJ. The pulse duration can be compressed to sub-50 fs behind the amplification stage. WebRenal artery stenosis (RAS), or renal artery disease, occurs when the arteries that carry blood to your kidneys get too narrow. Atherosclerosis (plaque buildup in your arteries) is the most common cause. RAS can lead to serious health problems, including high blood pressure, chronic kidney disease or kidney failure.
