Abstract

Michelson interferometry is used to investigate the pump-power dependent emission bandwidth of a THz emitter based on intra-cavity difference frequency generation in a two-color VECSEL. A multi-mode CW THz signal is found to result from the two simultaneously lasing groups of longitudinal VECSEL modes. Power-dependent experiments reveal a clear correlation between the THz signal bandwidth and the numbers of optical modes involved.
