Short summary
Short summary
THz systems are promising tools for non-destructive testing and material characterisation. High costs, which are mostly determined by the laser system, prevent the application in the market. By using monolithic dual-colour lasers, a significant cost decrease can be achieved. We discuss some of the typical drawbacks associated with these lasers. Furthermore, we present a complete THz system which is based on a dual-colour diode laser to show the capabilities for material characterisation.

Short summary
The generation and detection of radiation in the THz frequency range can be achieved with many different electronic and photonic concepts. Among the many different photonic THz systems the most versatile are based on diode lasers. In this paper we describe and review the different concepts and optimization ideas for diode laser based THz systems in order to achieve the best performance for different types of THz setups.
The generation and detection of radiation in the THz frequency range can be achieved with many...
