| 中文摘要 | The characteristics of the light filaments formed by lambda=400 nm blue femtosecond laser pulses are experimentally investigated. Both pre-focused and free propagation conditions are studied. The diameter, length and electron density were measured by using fluorescence signal imaging and longitudinal diffraction method. About 2x10(17) cm(-3) electron density in filaments was achieved with beam pre-focusing. In the free propagation case, the multi-filamentation can be observed over 70 m propagation distance, and the energy in the filament core is only about 30 mu J. The effects of energy reservoir on the filament core have been investigated by inserting a diaphragm in a selected single filament path to block the energy of the reservoir. The evolution of filamentation has been studied experimentally as a function of diaphragm size. The energy reservoir can be extended to about 10 mm from the filament core. The results indicate that the up conversion of laser is a possible way to enhance the utilization of laser energy for the generation of long filaments. |
