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...

(1.0.10) In femtosecond laser spectroscopy, a laser pulse is created which is so short that the entire pulse arrives at a fixed target in well under 1.0 ns. Suppose a 50.0 fs (f = 10-15) laser pulse with a circular cross-section is created. The power delivered by the pulse to a target is 10.0 kW, and the diameter of the beam is 20 µm. (a) What is the length of the pulse? (b) What is the intensity of the pulse?...

1. A high energy pulsed laser emits 1.50 nano second-long pulse of average power 1.70 × 10 11 W. The beam is cylindrical with 1.70 mm in radius. Determine the rms value of the B-field? 2. What is the total energy transported per hour along a narrow cylindrical laser beam 1.70 mm in diameter, whose E-field has an rms strength of 2.40×10−22.40×10−2 N/C ?

PRINTER VERSION 4 BACK NEXT ES Chapter 24, Problem 19 A lidar (laser radar) gun is an alternative to the standard radar gun that uses the Doppler effect to catch speeders. A lidar gun uses an infrared laser and emits a precisely timed series of pulses of infrared electromagnetic waves. The time for each pulse to travel to the speeding vehicle and return to the gun is measured. In one situation a lidar gun is a stationary police car observes...

(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...
