Abstract :
The present paper describes an alternative approach to the image forming, which is in a spatial modulation of the gain in the active medium, by the spatial modulation of the density of pump. The problems for the super-Rayleigh resolution are discussed and a possibility of gray scale image generation was shown. The fragmentation of the cross section of the Fabry-Perot cavity helps to suppress smoothening of the image edges during large objects generation. A numerical model of pump modulated lasing pixels (PMLP) was developed, the results of calculation being in good agreement with experiments.
