5.) Lasers can be used to drill or cut material. One such laser generates a series of high intensity pulses rather than a continuous beam of light. Each pulse contains 1.00 Joules of energy and lasts 18 nanoseconds. The laser fires 15 such pulses per second. (a) Find the peak power of the laser. (b) Find the average power output of the laser.

Part A High-power lasers are used to cut and weld materials by focusing the laser beam to a very small spot. This is like using a magnifying lens to focus the sun's light to a small spot that can burn things. As an engineer, you have designed a laser cutting device in which the material to be cut is placed 3.0 cm behind the lens. You have selected a high- power laser with a wavelength of 1.06 um. (This distance...

2. The lasers that you use in the lab have an intensity with a Gaussian profile, Ir) - loexpl-2/o], where lo is the peak intensity, at the beam's centre, is the radius at which the intensity drops to 1/e2 of the peak intensity, and r is the radial distance from the beam's centre. The laser beam has a total power of 1 mW and a half-width- at-half-maximum of an= 5 mm. Find the peak intensity, lo, in units of w/m2...
