Manufacture of lasers to date involves the use of complex technical processes. However, associate reported about a special way of working with liquid crystals, designed to greatly simplify it. These crystals are similar to those used in LCD displays, but the spiral structure of these molecules can act as an optical resonator cavity. Thus, under certain conditions, they gain the ability to optical excitation, generating a laser.
Early experiments such liquid crystals placed in thin gap between the two glass plates. A special polymer coating on the glass crystals aligns the molecules, and eventually received, scientists LCD laser. Such a method is bad need to comply with sterility and limitations in the choice of substrate - glass or silicon. Experts from Cambridge greatly simplify the process by creating a technology of applying a liquid crystal using a special printing equipment. Now it is possible without any problems to build arrays of lasers of different colors, virtually on any surface. The invention has been patented and its commercial implementation will deal with a subsidiary of the University of Cambridge - Cambridge Enterprise.
