Hi,

I am trying to find out what is going on with the AOTF.

With the RF not driving, my light is deviated around 5 cm and conserves the initial power. As far as I understand, it should not as this would correspond to the 0th order undiffracted light.

This AOTF was previously used for separating the different lines of an Ar ion laser. In my case, I have a blue solid state laser. I think it should not be a problem, as the wavelength almost matches with the one produced by the IR supplier (that's another doubt I have).

Anyone can help me, please? I am super intrigued!
