1) A laser beam enters a 12.0 cm thick glass window at an angle of 66.0° from the normal. The index of refraction of the glass is 1.42. At what angle from the normal does the beam travel through the glass? I know this one is 40.04 degrees. I am stuck on this one: 2) How long does it take the beam to pass through the plate?

1) A laser produces a Gaussian beam with a waist immediately outside the laser, with a beam radius of 5 mm, an average power of 1 Watt, and a wavelength of 1 шт. We wish to choose a lens that will focus this beam as tightly as possible, subject to the constraint that the depth of focus must be at least 1 mm. a) What focal length lens should we choose? (Assume an ideal thin lens with no aberrations.) b)What...

In a laser experiment, a laser beam i of vacuum wavelength has to propagate in air (n1 = 1) through a prism which is anti-reflex (AR) coated to minimize reflections. The prism is made from a glass which has an index of refraction of n3 = 1.3). The thin film is made from a higher index material with an index of n2 = 1.4. The angle of incidence between the laser and the prism is 0 = 30°. Which of...
