  • Quantum dots amplify light with electrical pumping

    In a breakthrough development, Los Alamos scientists have shown that they can successfully amplify light using electrically excited films of the chemically synthesized semiconductor nanocrystals known as quantum dots. The quantum dot films are integrated into devices much like the now-ubiquitous lig more

  • Need entangled atoms?

    Physicists at the National Institute of Standards and Technology (NIST) have come up with a way to link a group of atoms' quantum mechanical properties among themselves far more quickly than is currently possible, potentially providing a tool for highly precise sensing and quantum computer applicati more

  • The world's shortest laser pulse

    ETH researchers succeeded in shortening the pulse duration of an X‑ray laser to only 43 attoseconds. With a time resolution in the range of a few quintillionths of a second, they are now able for the first time to observe the movement of electrons during chemical reactions in slow motion. In order t more

  • Topological lasing

    Optics Resonant cavities that confine light are crucial components of lasers. Typically, these cavities are designed to high specification to get the best possible output. That, however, can limit their integration into photonic devices and optical circuits. Bahari et al. fabricated resonant more

  • Chaos-assisted broadband momentum transformation in optical microresonators

    The law of momentum conservation rules out many desired processes in optical microresonators. We report broadband momentum transformations of light in asymmetric whispering gallery microresonators. Assisted by chaotic motions, broadband light can travel between optical modes with different angular more

  • Spectral downshifting in Cr3+-Yb3+-Nd3+ doped Ba-Al metaphosphate glass: Role of Nd3+ as bridging ion

    Publication date: 1 December 2017 Source:Materials Chemistry and Physics, Volume 202 Author(s): Debarati Ghosh, S. Balaji, K. Biswas, K. Annapurna Here, Cr3+ sensitized intense luminescence is obtained from Yb3+ ions in a series of newly formulated Cr-Yb doped Ba-Al metaphosphate glass more

Gain lasers

Gain lasers Gain (or amplification) in laser physics is a process, where the medium transfers part of its energy to the emitted electromagnetic radiation , resulting in an increase in laser power. This is basic principle of all lasers . Quanti ... more
