On the basis of theoretical and experimental researches, analysis of scientific and technical literature the technical requirements to the basic blocks of an absolute atom gravimeter in variant A of the device with the minimum uncertainty of results of measurements of 5 microGal and variant B of the device with the minimum uncertainty of 10 microGal are defined. Basing on developed technical requirements and physical schemes of laser radiation sources, the high frequency stable laser prototypes for cooling atoms, forming of optical elements of an atomic interferometer were made. The laser system for registering the state of atoms at the interferometer output and electronics for controlling radiation parameters were developed and laser experimental samples were made.
