Diode Laser Packaging
The miniature sizes of diode lasers, require special packaging to enable people to use them with comfort. There are many kinds of packaging, but the standard is similar to a transistor package, and includes in the package the basic collimating optics to create a useable beam (see figure 6.29).

To get high power from diode lasers, special arrays of diode lasers were developed. These diode arrays emit synchronized radiation together, and output power of tens of watts is available. Although the radiation is emitted from many diode lasers, they are optically coupled such as it is possible to get coherent laser output out of these special lasers.
