Hey guys
I'm trying to understand the diode output power specs and how that relates to supply power.
If we take one of the p73 images from DTR as an example, the current of 1.3A produces an output of 1.105 W (image below). Given the diode has a 2.2V drop, power to the diode as I understand is 2.86W. Does this 1.1W beam power mean that there is a loss of 1.7W as heat? What are the implications of this for a TEC in terms of sizing. Is a 2W TEC suitable for example.
Thanks
