Abstract: A method of using S-NBD2 for application in a infrared spectrum is provided. The method includes the steps of providing S-NBD2; forming the S-NBD2 into an optical device; and using the optical device in the near infrared spectrum.

Abstract: Broadband photodetectors, detector arrays, sensors and systems, capable of detection and sensing ultraviolet (UV), visible (VIS) and shortwave infrared (SWIR) wavelengths of light, are disclosed. The devices may operate over a wavelength range between about 0.2 ?m and 1.8 ?m. In particular, the devices include a dilute nitride active layer with a bandgap within a range from 0.7 eV and 1 eV and a luminescent layer.

Abstract: A system and method for decreasing the optical pathway length, varying the characteristics of a WBC system. Through the various embodiments and techniques described herein, high-brightness multi-wavelength output systems may be combined into a single laser system to achieve a more efficient and a higher quality weld between two weld partners. Additionally, the present disclosure provides methods and techniques that account for the differences between dissimilar metals, namely metals having dissimilar thicknesses, melting points, thermal conduciveness, and/or thermal expansion coefficients.
