Multiple laser cavities have been established in a single lasing medium. Single giant pulses with a time duration of 40 nsec have been emitted from each cavity and spaced less than 80 nsec to 4 μsec apart. The 0.4-mm spatial separation between the cavities indicates that many cavities could be established in a single lasing medium. Sequentially switching large numbers of cavities, repumping depleted regions, and reswitching could result in a high-repetition-rate giant-pulse laser system for use in photography and holography.
