| 英文摘要 | ultrafast carrier dynamics in al2o3/sio2 high reflectors has been investigated by uv femtosecond laser. it is identified by laser spectroscopy that, the carrier dynamics contributed from the front few layers of al2o3 play a dominating role in the initial laser-induced damage of the uv reflector. time-resolved reflection decrease after the uv excitation is observed, and conduction electrons is found to relaxed to a mid-gap defect state locating about one photon below the conduction band. to interpret the laser induced carrier dynamics further, a theoretical model including electrons relaxation to a mid-gap state is built, and agrees very well with the experimental results.. to the best of our knowledge, this is the first study on the pre-damage dynamics in uv high reflector induced by femtosecond uv laser.
