The most promising are lasers based on infrared d-p transitions of noble gases. It is promising to create a laser based on 2p-1s transitions of noble gases in shorter wavelength region, with higher quantum efficiency. It is necessary to solve deactivation problem of lower 1s-level, two of these levels are metastable, two are resonant, radiation is trapped on them. Lithium serves as a source of laser mixture pumping with products of 6Li(n,a)3H nuclear reaction, also effectively deactivates lower 1s-levels. The work describes experimental facility to study the possibility of laser action under gas mixtures excitation by 6Li(n,a)3H nuclear reaction products in the pulsed nuclear reactor core.
