摘要：

Experimental studies have been carried out to determine the limits of the detection of chemical elements ( manganese, magnesium, lead, strontium) in water, when plasma generated by femtosecond laser pulses on the aqueous solutions surface, depending on the parameters of laser radiation ( pulse duration, energy and the mode of focusing). The emission lines of chemical elements in plasma generated in a aqueous solution by Ti-Sapphire laser complex at a central wavelength of 800 nm, using focusing lenses with different focal lengths, and also for collimated beams under laboratory conditions are registered.
