Description
he plasma mirror, operating as a distinctive ultrafast switch on a sub-picosecond scale, poses a remarkable yet not fully elucidated switching behavior. The formation of a plasma is initiated by the interaction of an intense femtosecond laser pulse with a transparent material, swiftly increasing the reflectivity of the surface. This plasma mirror formation takes place on a time scale of sub-picosecond. It is investigated here the interplay between intense laser pulses and plasma mirrors by implementing of a pump-probe method based on the retrieval of spectrally encoded temporal information. The exceptional ultrafast switching capabilities exhibited by plasma mirrors unlock a spectrum of applications, ranging from high-speed data transmission to laser pulses characterization and temporal contrast enhancement.
