该项目的研究包括使用特制的飞秒激光脉冲进行相干控制的研究。研究的一部分集中在特殊设计的层状半导体材料内的控制。通过整形激光脉冲激发了GaAs/GaAl_1As超晶格结构中的量子力学电荷振荡,并寻找了增强这些激发的生长和脉冲条件。活动的第二部分侧重于产生定制的太赫兹电磁波形,该波形是通过用成形的飞秒脉冲照射超快光导天线产生的。
英文摘要
The research in this program consists of studies in coherent control using specially crafted femtosecond laser pulses. One portion of the research focuses on control within specially designed layered semiconductor materials. Quantum mechanical charge oscillations in GaAs/GaA1As superlattice structures are excited through shaped laser pulses, and growth and pulse conditions are sought for which these excitations can be enhanced. The second part of the activity focuses on the generation of tailored THz electromagnetic waveforms produced by illuminating ultrafast photoconductive antennas with shaped femtosecond pulses.
