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