The idea to accelerate the charged particles in a plasma medium using collective plasma fields belongs to Budker, Veksler, and Fainberg. Later on, another acceleration schemes were proposed including the laser plasma acceleration. In our earlier work we studied the possibility of employment of ultrarelativistic monoenergetic electron and proton bunches for generation of high plasma wakefields in dense plasmas due to Cherenkov resonance plasma- bunch interaction. We estimated various paramaters at which the maximum amplitude can be generated at the given plasma and bunch parameters [1]. In our present work, we discuss another scheme of amplification of a plasma wave using a laser at the qualitative level. Namely, we make an estimation of plasma, injected electron bunch parameters, maximum amplitude of the generated electric field, determine condition for the electron trapping by the laser-induced plasma wave at which the maximum electron acceleration energy can be gained. As the basis parameters we use those set in plasma acceleration experiment at SPARC_LAB facility of INFN-LNF, Frascati, Italy, with external electron Injection [2]. [1] A. A. Rukhadze and S. P.
