Picosecond and Femtosecond Spectroscopic Instrumentation for Ultrafast Spectroscopy and Lasers

摘要

The Institute has acquired state-of-the-art ultrafast lasers and diagnostic instrumentation to upgrade its facilities and capabilities. A femtosecond mode locked CPM dye laser - dye amplifier system was substantially improved by the addition of new YAG laser pump. This femtosecond system will be used in the study of ultrafast processes in semiconductor microstructures and alloys. A multichannel Raman spectroscopic system was installed for use in the study of transient Raman effect in semiconductors and shock wave induced processes. An ultrafast streak camera was acquired for photoluminescence kinetic studies in semiconductor alloys and microstructures with a time resolution of 2 ps.
