Effects of pulsed laser parameters such as laser wavelength, beam spot size, pulse energy and pulse duration on threshold energy in laser simulating Single Event Effect testing are analyzed.
One of the most key problems in laser ablation is that of mastering the relativity of ablation threshold and wavelength, maximizing ablation rate, while simultaneously minimizing heat damage.
激光消融技术的关键在于掌握消融阈值与辐照波长的相关性，获得大的消融率和减少热损伤等等。
