Does this mean that the pulse energy remains the same under cutoff frequency? I have a YDFLP-100-M7-M-R laser source which specifies 1.5mJ as max pulse energy. According to the cutoff frequencies this can only be achieved at 350ns and 500ns as the cutoff frequency is 67kHz here (100W/67kHz=1.5mJ). I always thought the pulse energy would lower with frequencies below cutoff because the output power would lower, but this is not the case then?
