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 کاملMicroengineering Laser Plasma Interactions at Relativistic Intensities.
We report on the first successful proof-of-principle experiment to manipulate laser-matter interactions on microscales using highly ordered Si microwire arrays. The interaction of a high-contrast short-pulse laser with a flat target via periodic Si microwires yields a substantial enhancement in both the total and cutoff energies of the produced electron beam. The self-generated electric and mag...
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...
