Mirror Laser Discharge 1.0 mm beam Partial mirror Electrodes Power supply Review A helium-neon laser (λ = e33 nm) is built with a glass tube of inside diameter 1。0 mm. as shown in (Figure 1). One mirror is partially transmitting to allow the laser beam out. An electrical discharge in the tube causes it to glow like a neon light. From an optical perspective, the laser beam is a light wave that diffracts out through a 1.0-mm-diameter circular The angle...
A helium-neon laser emits a 2.0-mm-diameter laser beam with a power of 2.0 mW . Part A What is the amplitude of the electric field of the light wave? Express your answer with the appropriate units. Part B What is the amplitude of the magnetic field of the light wave? Express your answer with the appropriate units.
A helium-neon laser produces a beam of diameter 1.75 mm, delivering 2.90 x 1018 photons/s. Each photon has a wavelength of 633 nm (a) Calculate the amplitude of the electric field inside the beam. kV/m (b) Calculate the amplitude of the magnetic field inside the beam (c) If the beam shines perpendicularly onto a perfectly reflecting surface, what force does it exert on the surface? nN (d) If the beam is absorbed by a block of ice at 0°C for...
A He-Ne laser beam has power 1 mW and beam diameter 1 mm. Determine the electric field amplitude in the light wave, assuming that the light intensity is uniform across the beam profile.
