This work is dedicated to investigation of laser evaporation of samples in flame. Double volume nitrogen laser (λ=337,1nm, τ=8ns, Е=20mJ) was used in the experiment. Objects of analysis were high purity GaAs, rocks and aqueous solutions of Al, Na. Two excitation schemes for the atoms Al, Na were realized in the flame of acetylene-N20 and propane-butane-air respectively. Laser evaporations of samples was suggested from graphite rod groove. Optimum disposition of laser beam and discharge of burning gas and oxidant is found for atoms Al and Na in proportion 1:6 and 1:28 respectively. The detection limits of Al and Na in aqueous solutions were 8∙10 -7 % and 1∙10 -7 % respectively.
