A new laser frequency comb soon may be able to answer one of the most intriguing scientific questions: Are there other earthlike planets in our galaxy capable of supporting life as we know it? A collaboration of the National Institute of Standards and Technology (NIST), the University of Colorado at Boulder and Penn State University brings together the best of laser science, frequency combs and precision astronomical instrumentation. The researchers’ goal is to determine whether life might exist on other planets, said Scott Diddams, a NIST physicist and co-creator of the frequency...Read full article

    The study and the interpretation of the infrared emittances of celestial bodies and phenomena.
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
    An optical instrument for forming the spectrum of a light source and recording it on a film. The dispersing medium may be a prism or a diffraction grating. A concave grating requires no other means to form a sharp image of the slit on the film, but a plane grating or a prism requires auxiliary lenses or concave mirrors to act as image-forming means in addition to the dispersing element. Refracting prisms can be used only in parallel light, so a collimating lens is required before the prism and...
