A project at Macquarie University has demonstrated a way to narrow the linewidth of a laser beam by a factor of over ten thousand.Published in APL Photonics, the technique offers a promising route toward ultra-narrow linewidth lasers for potential use in a wide range of pump-pulse systems.Laser linewidth measures how precisely a beam of light maintains its frequency and color purity, and narrow-li...
The attosecond level ultra short laser pulse provides a powerful method for detecting and imaging ultra short processes, such as the motion of electrons in atoms and molecules.Although ultra short laser pulses can be generated, generating ultra short and high-energy pulses is a continuous challenge. In order to expand the photon energy, photon flux, and continuous bandwidth of isolated attosecond ...
Recently, scientists from the National Ignition Facility at Lawrence Livermore National Laboratory in California produced a burst of energy by bombarding hydrogen pellets with 192 laser beams, briefly reproducing the fusion process that powers the sun. This is a repeat of an experiment in December last year, but this time the scientists generated more energy, with a gain almost double that of the ...
The ocean covers over 71% of the Earth's surface, and so far humans have only explored about 5% of the ocean. This means that there are still 95% of the depths of the ocean that we know nothing about, making it the most mysterious and unknown place on our planet.600 years ago, Zheng He led a fleet to play the prelude to the era of great navigation, laying the foundation for us to understand the wo...
Recently, Laserline, a leading semiconductor laser manufacturer in Germany, announced that it has completed the acquisition of a 70% stake in WBC Photonics, a Boston based laser technology expert, marking a significant strategic expansion for Laserline. Through this transaction, Laserline not only expands its product portfolio to include blue laser systems with excellent beam quality (better tha...
