Investigation of emission spectra of plasma generated by laser pulses on Xe gas-jet targets

The paper discusses the results of studying the emission spectra and absolute radiation intensities of laser plasma generated by laser pulse on a xenon gas-jet target. A Nd:YAG laser, λ = 1064 nm, τ = 5.2 ns, E pulse = 0.8 J was used. The spectral range 3–20 nm was studied. Gas-jet targets were for...

Zusammenfassung:	The paper discusses the results of studying the emission spectra and absolute radiation intensities of laser plasma generated by laser pulse on a xenon gas-jet target. A Nd:YAG laser, λ = 1064 nm, τ = 5.2 ns, E pulse = 0.8 J was used. The spectral range 3–20 nm was studied. Gas-jet targets were formed by a supersonic conical nozzle. Emission spectra of laser plasma were obtained and interpreted. Absolute radiation intensities were determined in a number of spectral bands under various conditions of gas-jet target excitation.
