Well, we were able to connect the power meter to the computer and take data for our laser diode system. We checked the power stability of the diode with respect to time. It appears that we are not supplying enough power to the temperature controller so that it keeps the temperature of the diode stable.
We didn't capture temperature data simultaneously but, I sat by the system and noted when the temperature increased. In both cases, when the temperature increased, the diode power decreased.
I'm not sure if this is stable enough for tweezing. If not, then we are saved by the EOM we will use since it will stabilize the beam output.
