There is a great variety of different semiconductor lasers, spanning wide parameter regions and many different application areas: Small edge-emitting laser diodes generate a few milliwatts (or up to 0.5 W) of output power in a beam with high beam quality.They are used e.g. Changing the compositional mixing ratio of one of the elements creates more material flexibility with the concomitant increase in fabrication complexity. The BDL Series is a high power direct diode turn-key system available in wavelengths of 915nm or 976nm. Typically, the dopant atom is similar in size to the intrinsic semiconductor atom but has either one fewer or one greater electron in its valence shell. The WSLD wavelength options span from 405nm to 1920nm, with output powers in the range of 20mW to several watts, packaged in standard C, E, and H-Mount packages, as well as a variety of TO-can options.
