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.
