Although the popularization of astronomy in the last decade and the International Year of Astronomy, celebrated in 2009, there's a great lack in respect of quality instruments for astronomical disclosure. Thinking in this research about it, we intend to recuperate and elucidate a technique long forgotten: the metal mirror amateur telescope, once was done in the first reflecting telescopes. However, with the resources available today and given the high purity of the materials, our results were better than that obtained by the pioneers. We developed and built a large aperture telescope (250 mm diameter) and very bright (focal ratio = 4.0), versatile and portable. In our study was described step by step the process to fabricate the telescope. Through its first images captured of the Moon, we can illustrate its versatility both for use in outreach events and for use in amateur astronomy, because it is a primary focus capture system and can run registration of various astronomical events

The objective of the present work was to study the control of the dynamics of diatomic heteronuclear molecules interacting with electric fields created by lasers. Specifically in this work, the molecular photoassociation phenomenon will be analyzed. At this phenomenon, the atom's relative movement is described by a particle that moves in a morse potential well under the influence of an external time dependant force related to the external field. Based on the optimum control theory (OCT), it is presented at the present work laser pulses that alternate a given initial molecular state to a desirable end state, wich in this work was represented by the minimization of a cost functional that indicates how close. To do so, a computational sistem know as Genetic Algorithm (GA) was developed that can be characterizes as an extremelly eficient technique capable of scanning the solutions space and find results close to the optimum solutions
