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 کاملEffect of prepulse laser wavelength on EUV emission from CO2 reheated laser-produced Sn plasma
We investigated the role of prepulse laser wavelength on extreme-ultraviolet (EUV) emission and ionic debris generation. A 6 ns Nd:YAG laser operating at 266 nm was used to generate a pre-plasma that was then reheated by a 35 ns CO2 laser pumping pulse at 10.6 μm. At an ideal delay time, improvement in EUV conversion efficiency (CE) of up to 30 % was seen compared to the CE from the pumping pul...
متن کاملRecombination effects during expansion into vacuum in laser produced Sn plasma
The distance over which the charge state distribution evolves during the expansion of laser produced Sn plasma in vacuum is investigated experimentally. This distance is found to be less than 6 cm with a planar target irradiated by a 1.064 m laser at 8.3 1011 W /cm2 but greater than 60 cm when a 10.6 m laser at 2.5 1010 W /cm2 is used. The difference is attributed to the laser wavelength depend...
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 کاملMulticharged carbon ion generation from laser plasma.
Carbon ions generated by ablation of a carbon target using an Nd:YAG laser pulse (wavelength λ = 1064 nm, pulse width τ = 7 ns, and laser fluence of 10-110 J cm-2) are characterized. Time-of-flight analyzer, a three-mesh retarding field analyzer, and an electrostatic ion energy analyzer are used to study the charge and energy of carbon ions generated by laser ablation. The dependencies of the i...
