DILAS Diodenlaser GmbH

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).
