Proton acceleration by relativistic self-guided laser pulses
- Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)
Energetic protons and ions can be produced by the irradiation of a μm-thick solid target with an intense laser pulse via Target Normal Sheath Acceleration (TNSA). Typically the maximum proton energy increases with decreasing target thickness. However, amplified spontaneous emission (ASE) from the drive laser system may alter thinner targets before arrival of the main pulse and limit the attainable proton energy. Here we experimentally test a method of reducing ASE intensity and increasing TNSA proton energy by using relativistic self-guiding in an underdense plasma.
