  • Abstract
    Coherent zone folded acoustic phonons in terahertz quantum cascade laser (QCL) structures are investigated by high-speed asynchronous optical sampling. This method is based on two Ti:sapphire lasers with repetition rates of ~1 GHz respectively. The time delay between pump and probe pulse is achieved by an offset in repetition rate of 5kHz. This allows for fast scanning times without moving mechanical parts.
