摘要

The dependence of harmonic emission from a solid on the carrier envelope phase (CEP) is discussed by numerically solving the time-dependent Schr(o)dinger equation.The harmonic spectra periodically exhibit three distinct oscillating structures,which indicate the different dependences of the cutoff energies on the CEP.Furthermore,with time-dependent population imaging and the populations of different energy bands,the underlying physical mechanism is explored.
