80W 885nm Laser Diode Single Bar Array

Single bars diode laser are available in unmounted laser diode bars or mounted in conductively or actively cooled packages. Most diode bars operate in the wavelength region from 755 to 860 nm or between 940 nm and 980 nm. The wavelengths of 808 nm (for pumping neodymium lasers) and 940 nm (for pumping Yb:YAG) are most prominent. Another important wavelength is around 975–980 nm for pumping erbium-doped or ytterbium-doped high-power fiber lasers and amplifiers. A typical passively cooled diode is offered on a CS mount, a standard package that is compatible with a thermoelectric-cooler (TEC) based mounting fixture. The CS mount is appropriate for quasi-CW (QCW) and medium power CW operation. For active water cooling, it use micro-channeled heat sinks. Multiple bars can be stacked in the horizontal or vertical direction to increase the output power.
