Determination of Charge State, Energy and Angular Distributions of Tin Ions Emitted from Laser Produced Plasma Based Euv Sources. Determination of Charge State, Energy and Angular Distributions of Tin Ions Emitted from Laser Produced Plasma Based Euv Sources
We have performed time of flight (TOF) analysis to determine the intensity of ion distribution from tin based plasma for a range of charged tin ions (Sn–Sn). A Nd:YAG laser operating at 1064 nm with a full width at half maximum pulse duration of 5.2 ns was used to create the plasma under vacuum with a base pressure of 10−6 Torr. The plasma formation occurred on a custom made optical system, whi...
متن کاملCharacteristics of Ions Emission from Ultrashort Laser Produced Plasma
The dynamic characteristics of the ions emitted from ultrashort laser interaction with materials were studied. A series of successive experiments were conducted for six different elements (C, Al, Cu, Mo, Gd, and W) using 40 fs, 800 nm Ti: Sapphire laser. Time-of-flight (TOF) ion profile was analyzed and charge emission dependencies were investigated. The effects of incident laser interaction wi...
متن کاملAngular emission of ions and mass deposition from femtosecond and nanosecond laser-produced plasmas
We investigated the angular distribution of ions and atoms emanating from femtoand nanosecond laser-produced metal plasmas under similar laser fluence conditions. For producing plasmas, aluminum targets are ablated in vacuum employing pulses from a Ti:Sapphire ultrafast laser (40 fs, 800 nm) and an Nd:YAG laser (6 ns, 1064 nm). The angular distribution of ion emission as well as the kinetic ene...

متن کاملMitigation of fast ions from laser-produced Sn plasma for an extreme ultraviolet lithography source
The authors present evidence of the reduction of fast ion energy from laser-produced Sn plasma by introducing a low energy prepulse. The energy of Sn ions was reduced from more than 5 keV to less than 150 eV nearly without loss of the in-band conversion from laser to 13.5 nm extreme ultraviolet EUV emission as compared with that of a single pulse. The reason may come from the interaction of the...
