Compare Photodiode 12599 and 12595

We report the noise laser measured with 12595 (R = 0.056) and 12599 (R=0.050).
Parameters:
G (pre-amplifier) = 1000
Power on the Photodiode = 200 mW

We have get a DC voltage of 7.20 for 12595 and 8.43 for 12599.

The measurements show that there is not a big difference in the performances of the two photodiodes. I think that the responsivity of the 12599 is not 0.050 but 0.059, we should check on the datsheet. But it is rather intuitive, since if the power on the PDs is the same, than the output DC voltage is proportional to the responsivity: higher DC voltage means higher responsivity.

We should compare these noise curves with those recorded a few months ago with the "standard" RF driver. Anyway, it seems clear that the huge peak at 576 Hz is no longer present in the spectra.
