Abstract

We propose and demonstrate "double pump" terahertz time-domain spectroscopy as an alternative technique to obtain information on the carrier lifetime of low temperature-grown gallium arsenide (LT-GaAs). Initial results show good agreement with data obtained from standard transient reflectance measurements done on the same LT-GaAs samples.
