Hello
I want to measure the pulse length of a nanosecond laser(at 532nm Nd-
Yag) with a photodiode.
I could not find the correct photodiode to measure it.
Our lasers beam length is approximately 4-5 nanoseconds but I don't
know the exact length and I wanna learn it.
Can you suggest me a detector anf manufacturer for measuring it.
If you have another idea to measure the pulse width can you let me
know?
Thanks

A fast biased PIN detector like a Thorlabs DET25K should work; the
claimed risetime is 7 ps, which is plenty fast for ns pulses.

I looked that detector its risetime is 1 ns not 7ps.
Thanks.
