| 中文摘要 | different conical emission (ce) patterns are obtained experimentally at various incident powers and beam sizes of pump laser pulses with pulse durations of 7 fs, 44 fs and 100 fs. the results show that it is the incident power but not the incident power density that determines a certain ce pattern. in addition, the critical powers for similar ce patterns are nearly the same for the laser pulses with the same spectral bandwidth. furthermore, as far as a certain ce pattern is concerned, the wider the spectral bandwidth of pump laser pulse is, the higher the critical power is. this will hopefully provide new insights for the generation of ce pattern in optical medium. |
