    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.
    Laser diodes work best when cool—different cooling approaches work best for different laser powers.

    FIGURE 1. These unmounted pump laser-diode chips made by OSRAM Opto Semiconductors include high-power quasi-continuous-wave (QCW) bars (top left), low-fill-factor CW bars (top right), high-power CW bars (bottom left), and tailored mini-bars (bottom right).
    Laser diodes are efficient, narrowband, bright, and long-life, making them the ideal laser-pump source, and can be made to produce extremely high optical powers.
