If clockwise polarized light passes through the fiber without twisting the phase, the output is counterclockwise polarized light and the phase is clockwise twisted. By adding these elements to the laser pointer, the polarization twist (rotation) is controlled in the twisting direction of the orbital angular momentum, and the output is also controllable. “We like to…

Usually the laser can’t tell if the light is clockwise
It has been decades for laser pointer to control spin to produce light, but the orbital angular momentum produced in lasers is not so simple. The optical orbital angular momentum is created by twisting the phase of light into a spiral shape, forming a spiral shape. Because the closer to the center of the beam, the distortion…
Scientists realize a twisted laser pointer beam
Researchers at the University of Witwatersrand used the geometric phase of a laser pointer to achieve for the first time a method of changing the orbital angular momentum of a laser beam. “Nature Photonics” NaturePhotonics magazine published the research results of this new type of laser discovered by researchers in South Africa and Italy, which can produce…

Using the method of changing the pulse waveform of the laser pointer
In the process of promoting the rapid development of the optoelectronic industry in the future, the combination of laser pointer technology and other technical application fields has the following aspects: Laser chemistry: The traditional chemical process is generally to mix the reactants together, and then often need to heat (or add Pressure). The disadvantage of heating is…
Use high-energy lasers for practical purposes
Two projects currently underway in Japan aim to use high-energy laser pointer for practical purposes. One of these projects is a government-funded innovation project initiated by the Japanese Cabinet in 2014. The project was led by Yuji Sano, the former chief engineer of Toshiba, through cooperation with Osaka University and the Japanese Institute of Physics and Chemistry…
