Unformatted text preview: o between the fast and slow rays for a ruby laser ( = 694.3 nm). Assume the cell is at 45 o to the laser polarization to begin with. 3 (a) What angle should a HeNe laser beam make relative to the normal to the surface of an acousto-optical modulator operated at 40Mhz with a acoustical wavelength of 60 m? 4 Assume light from a HeNe laser hits a single slit 0.5 mm wide by 3 cm long. Light from the slit is focused by a f=50 cm lens. Calculate the location (distance from the central maximum) of the first minimum and first maximum (after the central one) in the projected image....
