(8%) Problem 11: Lasers can be constructed to produce an extremely high-intensity electromagnetic wave for a very brief time Such lasers are called "pulsed lasers". They are used to ignite nuclear fusion, for example. Such a laser may produce an electromagnetic wave with a maximum electric field strength of 0.18 x 101 V /m for a time of 0.75 ns Randomized Variables Eo 0.18 x 1011 V/m t= 0.75 ns 33% Part (a) What is the maximum magnetic field strength...
Very short pulses of high-intensity laser beams are used to repair detached portions of the retina of the eye. The brief pulses of energy absorbed by the retina welds the detached portion back into place. In one such procedure, a laser beam has a wavelength of 810 nm and delivers 250 mW of power spread over a circular spot 510 μm in diameter. The vitreous humor (the transparent fluid that fills most of the eye) has an index of refraction...
