Abstract
THz-TDS is a well-established technique for an extremely large variety of applications. However, many areas are stalled by the low average power of ultrafast laser driven THz sources. One example of an area that would immensely benefit from higher average powers is the exploration of molecular dynamics in liquids using both linear and nonlinear spectroscopy, which is hardly possible using currently available lab-based THz sources (with typical average powers <1 µW), due to the extremely high absorption of liquids at THz frequencies. For this and many other fields an increase in the average power of lab-based THz-TDS is a crucial milestone.
