Wide stripe single and dual wavelength mode semiconductor diode lasers
Wide stripe semiconductor lasers have a wide variety of applications in remote sensing, in materials processing applications such as drilling and welding, and as pumps for gas lasers. The emission spectra of simple cost-effective Fabry-Perot (F-P) lasers tends to be very broad, i.e. in the 5-10 nm …

Growth and characterization of mid-infrared phosphide-based semiconductor diode lasers
A diode laser emitting at mid-infrared wavelength (2~5 pm) is an ideal light source for petrochemical or industrial-important gas sensing. Antimony-based III-V compound semiconductor material is the most prominent pseudomorphic epitaxy candidate for this application. However, phosphide-based …
