High harmonic generation (HHG) in solids reflects the underlying nonperturbative nonlinear dynamics of electrons in a strong light field and is a powerful tool for ultrafast spectroscopy of electronic structures. Photocarrier doping allows us to unde

Floquet engineering is a promising way of controlling quantum system with photon-dressed states on an ultrafast time scale. So far, the energy structure of Floquet states in solids has been intensively investigated. However, the dynamical aspects of

Solid-state high-harmonic generation (HHG) is the most striking process that reflects emergent coherent electron dynamics under strong infrared laser field [1] - [4] . The microscopic origin of HHG is often theoretically separated into two contributi

Transition metal dichalcogenides (TMDs) are promising 2D semiconductor in optoelectronics. Due to the reduced dielectric screening, strong bound excitons that are even stable at room temperature exist in these materials and have strong influence on o

Monolayer (1L) MoSe 2 is a two-dimensional direct-gap semiconductor. Due to the low dimensionality and reduced dielectric screening, careers experience stronger Coulombic interaction than that in conventional bulk materials, which results in excitoni

We have investigated the photo-carrier doping effect on high-order harmonic generation in monolayer WSe 2 . The intensity change of harmonics induced by the photo-carrier doping suggests that the interband and intraband mechanism is comparable in the

Optical sum-frequency generation spectroscopy reveals a clear dipole-inactive $2p$ exciton peak in hBN-encapsulated monolayer WSe 2 under excitation with broadband picosecond near infrared laser pulses $(\hslash\omega=0.56\sim 1.3\text{eV})$ . The sp
