High energy single-frequency laser source at 780 nm can be used for next generation high spectral resolution lidar to accurately characterize and discriminate aerosol type and significantly improve both measurement retrievals and modeling on climate. Compact and robust single-frequency lasers at 780 nm can also be used by NASA for airborne and spaceborne laser cooling and manipulation of Rubidium, which has been extensively used in atomic vapor based instruments for sensing and metrology.
A 780 nm single-frequency laser can be locked to the transition of Rubidium to be a very stable secondary frequency reference (rubidium oscillator) for maintaining frequency accuracy in cell site transmitters and other electronic transmitting, networking and test equipment. Single-frequency fiber lasers at 780 nm can also be used for atomic interferometer, optical communications, atomic clock, GPS-free navigation, oil exploration, and mine detection. In addition, the 780 nm single-frequency lasers can be frequency doubled to produce high stability and narrow-linewidth UV lasers that have found applications in Raman spectroscopy, laser cooling and trapping, laser inspection, optical data storage, biomedical applications, and maskless laser lithography.
