PD 12595 & Low noise pre-amp Frascati
mdipaolo Thu Apr 23, 2009 1:46 pm
I report the measure of the noise of the 12595 measured with the low noise pre-amp and the laser noise (V/sqrt(hz) and RIN). The power onto PD was 16 mW. The responsivity is 0.056 and the gain od the pre-amp is 110.

1) I think of use power supply for the low noise pre-amp frascati. I think of put the pre-amp outside the lab laser.
2) I think of use the pre-amp frascati for the PD 12595.
4) AOM and the bench is already set; i must only connect the cable, switch on the AOM and measure the power on the PDs.
5) Measure the noise (RIN) in open loop.
6) Close the loop and measure the noise. Try for a minumum RIN.
PD to use: 12595 and TEC PD.
