As has long been known , the laser light is light that is uniform wave pattern consisting of rays that measure more subtle and normally can only be emitted in a straight line , but has since some time the experts knew that the pattern is superimposed on the laser can make laser is turned . The pattern can be designed in a certain way so that the number of lines that make up the light beam a laser beam can influence each other so that the laser shots turn . ” But it can not bend at an angle more than 10 degrees , because if the bend angle is more than 10 degrees then terbut light will be distorted and changed shape ” , according to Mordechai Sergev from the Technion – Israel Institute of Technology in Haifa .
He shared some of his colleagues are constantly trying to investigate further on this by studying Maxwell ‘s Equations which is the basic law of the behavior of electromagnetic waves . In theoretical calculations , they concluded that it is very possible to make the basic patterns in order to deflect the laser light over 180 degrees without distortion . These results have been published in Physical Review Letters by number documentation DOI : 10.1103/PhysRevLett.108.163901 . But this is still a theory .
Meanwhile , without their knowledge , a team of researchers led by John Dudley at the University of Franche – Comte ‘ Besancon France has melkukan test against this practice .
A shot of laser light that is able to turn themselves in at an angle like a boomerang successfully transmitted in an optical laboratory in France . Light with a diameter of only a few micrometers in size that can change the way the material to carve microscopic in size and it is hoped will be able to assist the surgeon makes an incision in the very thin in areas that required surgery but are difficult to reach with a straight laser beam on the patient’s body .
Dudley team of researchers managed to find a way to turn the corner of the laser can exceed the limit angle of 10 degrees . ” It is giving out the idea to us , that we will be able to make a greater angle curve again ” said a colleague of Dudley Francois Courvoisier .
Dudley team of researchers measuring several micrometers light fired at an angle more than 60 degrees by using a tool called the ” Spatial Light Modulator ” to ” superimpose ” the light interference pattern .
This work will be presented in the Journal of Optics Letter to come.
In their experiments , the research team uses a laser that can Dudley dibelokan is to carve and shape indentations in the glass . ” This will be very useful to create a prototype of a new design of optical equipment such as micro lenses for cameras and special projectors before you produce it en masse ” , said John Dudley . The surgeon can also use it to reach areas behind the operation of sensitive structures in the body of their patients .
Segev said that he hopes his team will be able to use these techniques to transmit light in turn full circle and use it to manipulate nanoparticles that can be loaded with drugs which can then be guided to treat specific areas in the body . During the laser light has indeed been successfully used as an ” optical trap ” to control nanoparticles , but by using a laser that can be deflected , then control of the nanoparticles will be developed to a higher degree .
