Up to six Q-switch pulses with interpulse separations of between about 2 and 100 mu s are extracted during single flashlamp pulses of a Nd: YAG laser (1.06 mu m) by opening the Pockels cell in up to six stages. The interpulse separations and output energies are adjustable for the individual pulses of the 10 Hz repetitive laser bursts. Measurements of maximum fiber transmission and stimulated backscattering are reported for 1 mm diam fused- silica step-index fibers.
