Israel Institute of Technology announced on the 29th that researchers at the school for the first time through experiments have shown that the interaction of water and light can emit laser in the previously considered irrelevant two research areas to build a "bridge." The new "water-wave laser" can be used to develop micro-sensors containing light waves, sonic waves and water waves, or microfluidic "chip lab" devices for cell biology research and new drug testing. Ordinary laser formation process is that atoms in the atom absorbs external energy is activated, in the form of laser radiation. For the first time, the team at Tal Carmon, director of the Center for Photonic Mechanics at the Institute of Mechanical Engineering at the Israel Institute of Technology, has shown that laser waves can also generate laser radiation when vibrated in liquid devices. In a paper published in the journal Nature Optics last week, they said water-wave lasers open up a whole new platform for scientists to study light and fluids in less than a hair-wide scale in the future Interaction between.

The frequency The difference causes the energy transfer between the light wave and the water wave to be inefficient, so that the laser radiation can not be generated. To overcome the problem of low energy transfer efficiency, the researchers created a device that transmits light to octanes (tiny alkanes containing 8 carbon atoms per molecule, 76 main components of gasoline) and tiny liquid formed by water drop. In this device, millions of "encounters" occur when light and water waves pass through a drop, and the accumulated energy causes the drop to radiate a water-wave laser. The researchers said that the interaction between light within the fiber and the tiny vibrations of the droplet surface is similar to resonance, just as the sound wave resonates multiple times over the surface through which it resonates. In order to increase this resonance effect, they deliberately chose a highly transparent liquid to enhance the interaction between light and liquid droplets. More importantly, the water droplets than the existing laser material has an unparalleled degree of softness, just apply a small light pressure, the degree of droplet deformation millions of times larger than ordinary photonic mechanical devices, so the laser Emission and laser intensity for more effective control.
