Question

A 10 mW infrared laser has a beam diameter of 2.0 mm. What is the rms value of the electric and magnetic field in the beam?

Accepted Answer

E_{rms} = 1.1 × $$10^{3} V/m$$, B_{rms} = 3.7 × $$10^{-6} T$$

Answer

E_{rms} = 1.1 × $$10^{3} V/m$$, B_{rms} = 2.6 × $$10^{-6} T$$

Answer

E_{rms} = 4.1 × $$10^{3} V/m$$, B_{rms} = 3.7 × $$10^{-6} T$$

Answer

E_{rms} = 4.1 × $$10^{3} V/m$$, B_{rms} = 2.6 × $$10^{-6} T$$
