摘要：

Coherent far-IR radiation is observed upon the generation of dense laser-driven plasma in a solid copper target. The coherent radiation demonstrates a strong half-cycle-pulse nature with temporal dynamics as fast as 150 fs. Comparisons between the data and radiation models are discussed. This measurement demonstrates a new method of performing ultrafast laser-plasma diagnostics in solid targets. (C) 2008 Optical Society of America
