摘要：

Generation of InAs-surface-emitted terahertz radiation by application of an ultrashort pulse 1060 nm parabolic fiber amplifier source is reported for the first time. The fiber amplifier delivers 100 fs pulses at a repetition rate of 75 MHz and an average power of maximum 12 W. This new excitation laser for surface-emitters generates high brightness broadband THz radiation ranging from 100 GHz to over 2.5 THz. THz detection is demonstrated based on two-photon absorption at low-temperature-grown GaAs dipole receivers. (C) 2005 Elsevier B.V. All rights reserved.
