Great interest is focused on femtosecond laser micro-nano fabrication due to the ultra-short time scale and ultra-high peakpowerdensity characteristics of the femtosecond lasers.
飞秒激光由于其超快时间特性和超高峰值功率特性在精密微纳加工领域引起了人们广泛的重视。
2
The changes of peak pressure depending on the laser powerdensity were studied.
讨论了激光功率密度的变化对冲击波峰值的影响。
3
The calculation indicates that the main parameter effecting laser output power is the peak electron temperature, while the limitation of repetition rates is related to the initial electron density.
