Paper Abstract

Several laser fusion applications require to transmit laser pulses of different wave-lengths (X. = 1,06 µm - 0,53 µm - 0,35 wri) through optical fibers onto a streak camera. Laser pulses of 10 ps duration have been propagated in a short length of optical fiber (12 meters). We describe in this communication the experimental set up of a high bandwidth liaison between a high power laser (104 to 109 W cm-2) and a picosecond streak camera. The utilisation of step index optical fiber (600 µm to 1500 μm diameter) is compatible with transport of high power density an much more convenient than the use of gradient-index or single mode fibers. Measurements have been done at 1,06 µm and 0,53 µm wavelengths ; we have demonstrated that 100 ps laser pulses can be transmitted without any significant temporal dispersion through these step index fibers.
