求教峰值功率以及平均功率
|
|
小弟最近看一篇文章里边有这样一句话 Then, we process the electrodes with a frequency tripled Nd:YVO4 laser, with 3 ns pulse duration, using a fluence range of 0–65 mJ/cm2. We set the slides on a translation stage, and defocus the laser to a spot size of 0.5 mm2 and raster the stage while pulsing the laser. The stage is rastered such that any given location experiences approximately 1000 pulses, which corresponds to an overall exposure time of approximately 30 μs. 请问如果按照65mJ/cm2来算，这个脉冲激光的峰值功率以及平均功率怎么算呀？我不太会算，真心求教，小弟学合金的不是好了解，实在没多少金币请见谅呀！ 峰值功率还好。。(065mJ/cm2*0.5mm2)/3ns, 但是平均功率不太理解呀，其中重复频率是1/30us呢还是1/（30us/1000）呀？ |
