FIGURE 1. The coefficient of performance (COP) of two laser-diode thermoelectric cooling modules by AMS Technologies, the TE-500 and TE-650, was characterized as a function of temperature difference (dT) and cooling capacity (Qc) using eight heat sources of 15 × 15 mm2 on top of the laser base plate and is given for an average temperature on the mounting plate.
