# Maxwell in Laser cavity

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

$\nabla x E = -j \omega \mu_0 H$
$\nabla x H = j \omega \epsilon_0 E$

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