Abstract


The purpose of this paper is to simulate the gas dynamic laser spends the energy stored in the vibrational degrees of freedom of the molecules arriving at the nozzle as follows. These molecular lasers lase based on vibrational and rotational transitions. Model equations have been developed by taking suitable control volume and are solved by using finite volume method. MATLAB Simulation results give the idea about of energy-level structure and small signal gain equations of HF and DF lasers; it then turns to population inversion generation and associated general fluid mechanic considerations. Then the model has been used to predict rates of excitations channels of pumping. Finally, the feasibility and effectiveness of the proposed method is demonstrated by computer.
