    Laser and Nonlinear Optics: an Overview
    (2006-06) Shimelis, Abebe; Ghoshal, Sib Krishna (Professor)
    The purpose of this project is to see the different nature and types of laser and nonlinear optics. Both laser and non-linear optics are the fruits of nineteenth century. Generally, this paper summarizes the operation and application of laser and non-linear optics. Upon irradiation with laser light of specific wavelengths and intensities optical fibers and bulk glasses undergo relatively slow (minutes to hours) changes, which result in new optical phenomena that were not present before irradiation. One of these phenomena is Second Harmonic Generation. Particularly in the first part of this project, from the meaning of laser to the type and uses of laser is going to be investigated. In the second part, the non-linear optics, which is entirely related, to laser will be examined
