Laser Maximum Power in according to the Chiller Temperature

I have observed that the efficienty of the Laser is maximum for chiller temperature between 16.1 °C and 16.8 °C; it isn't exactly 16.5 °C as indicated in the previous note.

I think there is one information missing from the graph: the temperature of the laser body. It could be easily measured by connecting the laser body temperature sensor directly to the auxiliary input of the chiller. In fact, the connector of the laser body temperature sensor is made in such a way that it exactly fits the connector of the auxiliary input on the back of the chiller. We could temporarily move the laser close to the chiller, so to avoid using long cables that could ontroduce an offset, and repeat the power measurement recording also the laser body temperature. In the future, we should also think to measure the laser noise as a function of the chiller set point and the laser body temperature.
