Abstract
A techinque for modulating the output signal of an acousto-optically Q-switched laser is disclosed. The switch is energized with an acoustic wave having a frequency equal to the approximate frequency spacing between longitudinal lasing modes of the laser. Among other advantages, the technique permits identification of lasers by length of resonator and through detection of the frequency of modulation of the laser output.
