Abstract
A pulsed laser having a laser gain medium of broadband output is tuned to essentially monochromatic output. An acousto-optic cell is driven with an acoustic wave which varies linearly in frequency, causing the laser beam to be resolved into a number of essentially monochromatic focal points. The focused beam of the desired wavelength is reflected to the output through one or more apertures which block out the unwanted wavelengths.
