FWM--TPA---FCA

FWM (Four-Wave Mixing), TPA (Two-Photon Absorption), and FCA (Free Carrier Absorption) are all important nonlinear optical effects. These effects are often studied and analyzed using mathematical models and simulations in MATLAB. If you have a specific question or need help with writing MATLAB code for simulating any of these effects, please feel free to ask and I'd be happy to assist you!
