Abstract:
The laser contrast ratio within picosecond timescales is one of the important parameters for laser acceleration. For a high laser contrast ratio, a 140 MeV monoenergetic electron beam with a charge of 44 pC is obtained by using a 20 TW Ti:sapphire laser. For a low laser contrast ratio, a low quality electron beam or no electron beam is generated, because the pre-pulse blows out plasma electrons and puts the plasma into disorder before the main pulse interacts with the plasma. The laser contrast ratio should be high enough in order to generate a high quality electron beam with a large amount of charge.
