ok, so I've seen the movie
where they aline a HEnE laser with a photodiode to hear the modulations in the photon stream.
i been trying to re-do it, and i just can't get it to work. I am NOT using a HeNe laser, I am using a normal laser from a pen, as i was sure the concept of the laseres "resonance" is the same, but as its not working I am beginning to doubt. I am not sure I am using a silicon diode either(got it from a friend,so can't check it, but its a very reflective diode, so again in theory, it should work.
can anyone explain me why its not working? is it the laser? is it the diode?
i really need this to work as its part of my bachelor project.
Best regards

thanks :)
