Chapter 33, Problem 026 In the figure, a laser beam of power 5.52 W and diameter D= 2.60 mm is directed upward at one circular face (of diameter d < 2.60 mm) of a perfectly reflecting cylinder. The cylinder is levitated because the upward radiation force matches the downward gravitational force. If the cylinder's density is 1.12 g/cm3, what is its height H?
Chapter 33, Problem 026 In the figure, a laser beam of power 3.85 W and diameter 2.60 mm is directed upward at one circular face (of diameter d < 2.60 mm) of a perfectly reflecting cylinder. The cylinder is levitated because the upward radiation force matches the downward gravitational force. If the cylinder's density is 1.71 g/cm', what is its height H? Number Units the tolerance is +/-5% Click If you would like to show Work for this question: Open...
A laser emits a cylindrical beam of light 2.6 mm in diameter. If the average power of the laser is 2.6 mW , what is the rms value of the electric field in the laser beam? (Units for the answer is kV/m)
A laser emits a cylindrical beam of light 2.6 mm in diameter. If the average power of the laser is 2.4 mW, what is the rms value of the electric field in the laser beam? Express your answer using two significant figures.
A laser beam of diameter d1 = 1.1 mm is directed along the optical axis of a thin lens of focal length +6.5 cm (see figure below). (a) How far from the lens will the beam be focused? (b) 1. A second positive lens is placed to the right of the first. Light emerges from the second lens in a parallel beam of diameter d2 = 3.8 mm. Thus the combination of lenses acts as a beam expander. Find the...

A laser pointer outputs a beam with a circular spot 4 mm in diameter. Its peak magnetic field is 5*10^-6 T. What is the beam intensity? What is the output power of the laser pointer?
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...
