THz spectroscopy, driven by ultrafast NIR lasers, finds broad applications but needs higher average powers for efficiency. Recent research explores high-power laser applications for THz generation, yet methods like optical rectification demand high pulse energies. Photoconductive (PC) emitters offer an alternative with intrinsic performance tied to accelerating static fields, reducing pulse energy requirements. Two types exist: photoconductive antennas (PCAs) and large area emitters (LAEs). PCAs offer high efficiency but limited power handling due to their PC gap, while LAEs with larger active areas can handle higher powers. My research focuses on combining the method of THz generation with laser development techniques borrowed from the field ultrafast laser science. The aim is to develop high power and high repetition rate THz sources to answer some of the physical questions addressed in our group.
