Investigation of coherent acoustic phonons in THz quantum cascade laser structures
Coherent zone folded acoustic phonons in terahertz quantum cascade laser (QCL) structures [1] are investigated by high-speed asynchronous optical sampling [2]. 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 a...
