Abstract: Water-cooled metal-halide lamps were constructed. The emission spectra were determined for lamps filled with Xe + Hg + NaI + RbI and Xe + Hg + NaI + TlI. The output power of a YAG:Nd³⁺laser was determined as a function of the pumping power supplied by lamps with different fillings. The differential efficiency of the laser pumped by a lamp containing an admixture of sodium and rubidium iodides was 3.5 and 1.5 times higher than the efficiencies obtained for pumping with xenon and krypton lamps, respectively.
