研究目的
Investigating the contribution of the cross section geometry to the active medium gain of the He-Ne laser.
研究成果
The method was tested for the Helmholtz equation solving with the homogeneous and inhomogeneous boundary conditions for cross sections that allow an analytical solution, and checked the several different cross sections in search of the cross section giving the maximum gain coefficient value. Further plans include complicating the model under consideration, taking into account the field intensity distribution in the resonator.
研究不足
The models were not analytical and demanded approximate calculations. Some experimental verification was carried out only in a rectangular cross section. The model needs to be complicated by taking into account the field intensity distribution in the resonator.
