A study was made of a neodymium glass laser with control of the pulse shape and duration in the nanosecond and subnanosecond ranges. The laser consisted of a master oscillator and an amplifying system. The time profile of a radiation pulse was shaped with an electrooptic deflector made of lithium niobate and a Pockels switch with two DKDP crystals in the amplifying system. Small-scale self-focusing in the amplifiers was suppressed by spatial filtering of the radiation. Pulses of duration 3 nsec and with an intensity difference up to three orders of magnitude were obtained at the laser output. The duration of the sharpened part of the pulse was approx.200 psec. The radiation energy at the output was as high as 10 J.
