Solving Maxwell's Equations in Laser Cavity | Tips and Troubleshooting

Click For Summary
SUMMARY

This discussion focuses on solving Maxwell's Equations within a laser cavity of length L. The user employs the phasor representation of the electric field, E(x,y,z)=e(x,y)e^{-j \beta z}, and the magnetic field, H=h(x,y)e^{-j \beta z}, while applying the curl equations: ∇ x E = -j ω μ₀ H and ∇ x H = j ω ε₀ E. The conversation emphasizes the importance of starting with waveguide equations and applying appropriate boundary conditions to achieve a solution.

PREREQUISITES
  • Understanding of Maxwell's Equations

Hello guys,

I've been trying to solve Maxwell's Equations in a laser cavity, with length L.
However I cannot...
I've searched over the net to find a proper solution but I couldn't.

I started by taking a field E(x,y,x,t)=E0 e(x,y)e-jw te-jb z.
I take the phasor E(x,y,z)=e(x,y)e-jb z and I put it in the Maxwell's equations

[itex]\nabla x E = -j \omega \mu_0 H[/itex]
[itex]\nabla x H = j \omega \epsilon_0 E[/itex]

where H=the phasor of the magnetic field=[itex]h(x,y)e^{-j \beta z}[/itex].

Any ideas? Please...
