Abstract

The direct observation of gamma-ray laser radiation on wavelength λ ≈ 0.2 nm have been carried out from tantalum-181 plasma, produced by picosecond ND:YAG laser (under an additional influence of external electric field and without them). It had been established that duration of such radiation in mode of ASR ("Amplification of Spontaneous Radiation") approximately equals 1-3 ns on the background of isotropic distribution of intensity the strongly directed components along micro plasma jets. Such gamma-ray laser radiation penetrates throw Be-filter (thickness 130 μm) from vacuum chamber into atmosphere, where the gamma-holograms were produced in closed box. So the coherence of generated gamma-ray radiation can be confirmed by the first our gamma-holograms production. Few examples of gamma-holograms and its images of different micro objects are considered. The constructed compact gamma-ray facility and developed gamma-ray holographic method will be very useful to experimental investigations in area of microbiology, genetics and etc.
