Abstract :
The emission of a quantum cascade laser can be synchronized to the repetition rate of a femtosecond laser through the use of coherent injection seeding. This synchronization defines a sampling coherence between the terahertz laser emission and the femtosecond laser which enables coherent field detection. In this contribution the sampling coherence is measured in the time-domain through the use of coherent and incoherent detection.
