Pulsars possess enormous energy, their energy reservoir is rotational energy. It is believed that plasma processes that provide emission generation in extreme environment of these objects are powered by their rotational energy. Search for effective mechanisms of rotational energy transfer to the magnetospheres is one of the actual central problems in pulsar astrophysics. In previous studies, we have found that action of relativistic time-dependent centrifugal force on magnetospheric plasma particles induces parametric instability, directly pumping the rotational energy of the central object into the natural oscillations of the plasma. Consequently, it is important to search for more channels of energy transfer from magnetocentrifugally excited Langmuir waves into the magnetospheres. The previous study of magnetocentrifugally driven waves showed that the time-scales of parametric instability are small compared to the escape times of resonant particles, ensuring high efficiency of amplification of the process, providing the exponential growth of the parametrically excited electrostatic field. In due course of time the electric field will inevitably reach the Schwinger limit, leading to the activation of pair-creation process. Taking into account that the process is energetically supplied from enormous reservoir of rotational energy, its efficiency must be guaranteed. This introduces thoroughly new scenario for particle production and emission generation in pulsar magnetospheres. The observations constantly discover new peculiar sources with different features that can not be explained in the framework of well-developed pulsar models. Consequently, the possibility of obtaining second efficient plasma production region farther from the star surface makes possible to consider more emission generation scenarios. This will provide development of more generalized emission model for pulsars that can explain various radiation patterns in the single theoretical framework, which remains one of the main issues in pulsar physics. This will play a significant role for getting closer to the development of a universal, single emission model for pulsars, which has long been the active main research problem in pulsar physics.
