An end-pumped and electrooptically tuned Nd : Ti : MgO : LiNbO 3 microchip waveguide laser is studied by using the self-consistent model and the conformal mapping method. The complex atomic susceptibility is used to describe the laser gain and pump absorption for applying the fast Fourier transform beam propagation method (FFT-BPM) to simulate. Using the conformal mapping method, the index change distributions in the waveguide, caused by the applied electric field, were evaluated. The optimal configuration for the microchip waveguide laser with various cavity lengths was designed. The output performances of the end-pumped and electrooptically tuned Nd : Ti : MgO : LiNbO 3 microchip waveguide lasers were simulated and investigated.
