Abstract. Characteristics for the generation of the second harmonic in homogeneous, collisional and magnetized plasma are investigated theoretically by solving the system of nonlinear equations for the fundamental and second harmonic extraordinary waves. The dependence of the efficiency of the wave frequency doubling on the distance from the plasma boundary and on the collisional frequency has been calculated.

GENERACIJA DRUGOG HARMONIKA U SUDARNOJ MAGNETOAKTIVNOJ PLAZMI
Teorijski su istraživane osobine generacije drugog harmonika u homogenoj, sudarnoj i manetizovanoj plazmi rešavanjem sistema nelinearnih jednačina za osnovni i drugi harmonik neredovnih talasa. Izračunavana je zavisnost efikasnosti dupliranja talasne frekvencije od rastojanja od granice plazme i od sudarne frekvencije.
