Density dependent exciton dynamics and L valley anisotropy in germanium
Markus Stein, Christian Lammers, Phillip Springer +4
Optical pump-THz probe spectroscopy is used to investigate the exciton formation dynamics and its intensity dependence in bulk Ge. Associated with the intra-excitonic 1s-2p transit…

Gain spectroscopy of a type-II VECSEL chip
Christian Lammers, Markus Stein, Christian Berger +9
Using optical pump-white light probe spectroscopy the gain dynamics is investigated for a VECSEL chip which is based on a type-II heterostructure. The active region the chip consis…
