LASER RESONATORS FOR NEW LASER PROFILES AND OPTICAL LOGIC GATES

Generation of new laser profiles which are fully defined inside the resonator and require no additional optical shaping presents a challenging task but promise a viable route for use in particle confinement, laser tweezers, magneto-optical and gravito-optical traps, optoelectronics and in communication technology. Here we will show how both linear and cylindrical laser profiles have been realized and emphases their application. We used a laser resonator consisting of two mirrors, gain medium CdSe nanoparticle in solution, and an additional optical component placed within the resonator that is ultimately responsible for the shape of the output laser profile. This optical component proved to be the most challenging part of the setup since it had to be almost completely transparent in order to achieve a laser effect. For pump beam we used a 532 nm nanosecond laser and got the output laser emission at 655 nm. We additionally used similar setup to achieve a NOT logical gate which, due to the use of the nanoparticles in solution and not the standard semiconductor elements, present a unique realization of completely optical logic gate. We will show that besides the relatively trivial realization of AND and OR logic gates this setup could also be used to create XOR gates which then allows for realization of a complete optical logical algebra for possible application in information processing.
