Exciting Explanation of Electric and Magnetic Fields in a Helium-Neon Laser Beam!

Are you curious about the fascinating world of lasers and their electromagnetic fields? Allow me to guide you through an exciting explanation of the amplitudes of the oscillating electric and magnetic fields in a typical helium-neon laser beam!

Let's start with the specifics - the laser beam in question emits light with a wavelength of 633 nm, a diameter of 1.0 mm, and a power of 1.0 mW. To determine the amplitudes of the electric and magnetic fields, we need to delve into the realm of physics and mathematics.

Calculating Electric Field Amplitude (Eo):

The amplitude of the electric field (Eo) can be calculated using the formula:

Eo = sqrt(2 * I / (εo * c))

After plugging in the given values and performing the calculations, we find that Eo is equal to 9.796 x 10^2 N/C.

Calculating Magnetic Field Amplitude (Bo):

The amplitude of the magnetic field (Bo) can be determined using the formula:

Bo = sqrt(2 * μo * I / c)

Upon substituting the values and carrying out the necessary computations, we obtain Bo as 3.266 x 10^-6 T.

The amplitudes of the electric and magnetic fields in the helium-neon laser beam are Eo = 9.796 x 10^2 N/C and Bo = 3.266 x 10^-6 T, respectively. These values showcase the intensity and characteristics of the electromagnetic fields in the laser beam.
