Question by cavenilvino: How can you work out peak power from average power?
If I power a laser using a pulse generator which I set to 680kHz with a pulse width of 105ns and amplitude of 1A; and subsequently measure the AVERAGE optical power produced as 3.3mW how can I work out what the peak power is?

Answer by biire2u
Since RMS values are usually the square root of two from the peak values, I think it is just done in reverse, multiply average power by square root of two (1.414).
Peak power = 3.3mW * 1.414 = 4.6662 mW
Give your answer to this question below!
680 KHz is 1.47µS so 105nS is 7.124% of the time
3.3/7.124*100= 46.32W
I think!
Hope this properly answers your question
PS
he square root of 2 is for sinewave only
