Abstract

The emission spectra of neon and argon gas jets in the range of 3–20 nm when excited by pulsed laser radiation have been studied. The Nd:YAG laser with λ = 1064 nm, τ = 5 ns, and Epul = 0.8 J has been used. A capillary with a diameter of d = 500 μm and supersonic conical nozzles with dcr = 145 μm, 2α = 12°, and L = 5 mm, and dcr = 450 μm, 2α = 11°, and L = 5 mm have been used to form the gas jet. Emission spectra for various gas targets have been obtained and decoded and the ions emitting in this spectral range have been determined. The line intensities in the spectra of the gas jets formed by different nozzles have been compared.

摘要

研究了在脉冲激光辐射激发下，氖气和氩气射流在3–20 nm范围内的发射光谱。使用了λ= 1064 nm，τ= 5 ns和Epul = 0.8 J的Nd：YAG激光器。已使用直径为d = 500μm的毛细管和dcr = 145μm，2α= 12°和L = 5 mm的超音速圆锥形喷嘴以及dcr = 450μm，2α= 11°和L = 5 mm的超音速锥形喷嘴形成气体射流。已获取并解码了各种气体目标的发射光谱，并确定了在此光谱范围内发射的离子。比较了由不同喷嘴形成的气体射流的光谱中的线强度。
