متن کاملAb initio self-consistent laser theory and random lasers
We review our recent work leading to steady-state solutions of the semiclassical (Maxwell-Bloch) equations of a laser. These are coupled non-linear partial differential equations in space and time which have previously been solved either by fully time-dependent numerical simulations or by using major approximations which neglect non-linear modal interactions and/or the openness of the laser sys...
متن کاملControlling mode competition by tailoring the spatial pump distribution in a laser: a resonance-based approach.
We introduce a simplified version of the steady-state ab initio laser theory for calculating the effects of mode competition in continuous wave lasers using the passive cavity resonances. This new theory harnesses widely available numerical methods that can efficiently calculate the passive cavity resonances, with negligible additional computational overhead. Using this theory, we demonstrate t...
متن کاملSteady-state Ab Initio Laser Theory and its Applications in Random and Complex Media
Steady-state Ab Initio Laser Theory and its Applications in Random and Complex Media Li Ge 2010 A semiclassical theory of single and multimode lasing, the Steady-state Ab Initio Laser Theory (SALT), is presented in this thesis. It is a generalization of the previous work by Türeci et al which determines the steady-state solutions of the Maxwell-Bloch (MB) equations, based on a set of self-consi...

We perform a first-principles calculation of the quantum-limited laser linewidth, testing the predictions of recently developed theories of the laser linewidth based on fluctuations about the known steady-state laser solutions against traditional forms of the Schawlow-Townes linewidth. The numerical study is based on finite-difference time-domain simulations of the semiclassical Maxwell-Bloch l...
