Laser-plasma interaction physics including absorption, plasma formation, heating, plasma expansion, and energy transport, are examined for 3-nsec Nd-laser irradiances between 10/sup 12/ and 10/sup 15/ W/cm/sup 2/. Efficient energy deposition and conditions favorable to ablative acceleration are found at 10/sup 12/--10/sup 13/ W/cm/sup 2/, whereas reduced absorption, hot electrons, and fast ions are seen at 7 x 10/sup 14/ W/cm/sup 2/. Suitability of the observed physics to pellet fusion is discussed.
