Second-Harmonic Generation Phenomena in "Green" Laser Pointer
By Rostyslav Danylo, Olena Polianska, and Yevheniia Chernukha, Taras Shevchenko National University of Kyiv, Kyiv, Ukraine


We present on the video a laser pointer. It’s a modern product permitting to indicate faraway objects. The idea of the video is to show the interior construction of the pointer to the audience. We want to describe the elements the pointer consists of and demonstrate product’s optical scheme. We saw up the frame of the pointer. We separate gradually different optical elements and describe their importance. In fact we see the edge of the gain media and the mirror deposed on it.
