High Average Power and Broadband THz Wave Generation Scheme Via Optical Rectification in 4-dimethylamino-N-methyl-4-stilbazolium tosylate Crystal

摘要

We obtained average THz power of 18μW using DAST crystal via optical rectification of femtosecond pulses. This power is more than two orders higher than the average THz power obtained from the typical photoconductive antenna.
