Abstract

The next generation of fusion lasers requires mirrors with laser damage thresholds of at least 40 J/cm for 10 ns laser pulses. Up to now, no deposition technique ha been developed to produce such mirrors. Best values realized today are around 30 J/cm for e-beam evaporated mirrors. R&D on conventional e-beam coating processes over the last 10 years has come up with marginal improvements in laser damage thresholds only. This aspect was the motive to investigate novel (unusual) deposition techniques which may provide the laser damage thresholds necessary.
