A continuous wave laser beam in free space carries a power of 15w and has a circular cross section with diameter 1mm. Calculate peak values of the oscillatory electric and magnetic fields Eo and Ho repectively.
Eox = ([tex]\mu[/tex]/[tex]\epsilon[/tex])^1/2 Hoy
Energy flow = 1/2 (HE + EH)
energy flow = | E x H |
E = Eo cos ([tex]\omega[/tex] t )
The Attempt at a Solution
Okay so i have the energy flow as 19098.593 Kj / s / m^2
I know energy flow = 1/2 \HE + EH ) = EH = |E x H| this energy flow is in direction of wave..
But i cant work out how to relate this to get the mag of electric field or magnetic field
