Very short pulses of high-intensity laserbeams are used to repair detached portions of the retina of the eye. Thebrief pulses of energy absorbed by the retina weld the detached portionsback into place. In one such procedure, a laser beam has a wavelengthof 810 nm and delivers 250 mW of power spread over a circularspot 510 mm in diameter. The vitreous humor (the transparent fluid thatfills most of the eye) has an index of refraction of 1.34. What average pressure would the pulse of the laser beam exert at normal incidence on a surface in air if the beam is fully absorbed?
design an ordinary end fire uniform linear array with only one maximum so that its directivity is 20 dB (above isotropic). The spacing between the elements is lambda/4 and its lenth is much greather than the spacing. Determine the (a) the number of elements (b) overall length of the array (in wavelengths) (c) approximate half-power beamwidth(in degrees) (d)amplitude level (compared to the maximum of the major lobe) of the first minor lobe (in dB) (e) progressive phase shift between the elements (in degrees)
Why is the static dielectric constant of some materials larger than their optical dielectric constant? How doesvdielectric constant vary with frequency?
A Fabry-Perot device contains two parallel part-reflective surfaces, each with a power reflection coefficient R = 0.9, separated by an air gap of 0.05 mm. The device is used at near-normal inci- dence with a transmission maximum at wavelength 600 nm. Calculate the coefficient of finesse, and the resolving power.
