This paper discusses a series of experiments performed with the LLL two-beam laser system, JANUS. The JANUS laser is capable of focusing approximately 500 Gigawatts of 1.06 ..mu.. power (40 J in 80 psec) on laser fusion type targets. In these experiments, the targets were deuterium tritium (DT) filled glass microshells with aspect ratios of 100 to 200. Targets of this type operate in what is commonly called the exploding pusher mode. The result is that the glass shell surrounding the DT gas (the thermonuclear fuel) effectively explodes, and consequently from geometry, also implodes and compresses and heats the DT gas to TN conditions. The advantages and disadvantages of the exploding pushers type target, as compared with the high density isentropic implosion target of the future, is illustrated.
