Thermal Transport Experiments at O.35 micrometer Laser Wavelength

摘要

Layered plane targets have been irradiated with O.35 mu m laser wavelength at the power level O.1 TW using the Nd-glass system Octal equipped with KDP tripling systems. Four beams were superimposed on a 150 mu m in diameter focal spot. Propagation of the thermal front (T >= 10 sup 6 K) was analysed by means of time-resolved recording of the sub-KeV X-ray target emission. A comparison to computer simulations shows that the results can be described by a flux limiter f = 0.03 +- 0.015. (ERA citation 12:006173)
