A collimated Gaussian light beam is focused to a spot by a lens. The diameter (2w) of the input beam is 100 microns. What is the diameter of the waist (2wo) of the focused spot if the wavelength of the light is 1550 nm and the focal length of the lens is 1.5 mm?

P3.4. The spot size is clearly extremely important in determining the power density of a focused laser beam, an important determi- nant of how it may be used in surgery. However, there is a basic limitation on how small a spot one can achieve with a given wavelength laser beam, ; a given diameter laser beam (D); and a lens with focal length, f. This smallest spot sizc is given by: where d is the diameter of the focused laser...

A 3 mW red ( = 670 nm) laser pointer produces a 2 mm diameter spot on a screen. a) If we place a f = 1cm lens before the screen, and the radius of curvature of the wavefront reaching the lens is 2 m, find the waist of the focused light. b) The intensity of the light at the center of the beam is given by Imax= 2P/πw2(in W/m2). Calculate the maximum intensity at the focal point. c) If...

A scientist requires the construction of a diffraction-limited telescope to image small dunes on Mars. The telescope will be mounted on a spacecraft instrument platform. The spacecraft will orbit Mars at an altitude of 400 km. The dunes are 2 m in diameter (horizontal size, as seen from above). The wavelength of instrument operation is 500 nm. The large-format detector is a CCD with 4096x4096 array of pixels, where each pixel is 30x30 microns in size. The scientist requires that...

A camera with a lens diameter D = 3 mm and a focal length of f = 4.25 mm. Assume the wavelength of light is 500 nm and the sensor in the camera is 5 mm x 5 mm and that each pixel has a size of 2μm x 2μm. A) If a vertical meter stick is located 5m from the camera and the image of the meter stick is in focus, how far from the lens is the sensor?...

Show the steps to calculate the Compton wavelength of the
electron (i.e. 2.4*10^-12) from equation 1.9 in the text.
Use this equation if necessary:
The Compton Eedl One of the characteristics of particles is that they can scatter off of each other, conserving both energy and momentum in the scattering process. If light truly does behave like a particle, it should be possible to observe such sc and to predict the change in the energy and momentum of the light...
