Sebastián Lavín Varela, young student and member of the Center for Optics and Photonics, CEFOP, of the University of Concepción, defended his thesis on Tuesday entitled “Experiments of light-atom coherent interaction in 85Rb and 87Rb isotopes using semiconductor lasers,” thus achieving the degree of Master of Science in Physics. The examination was rendered in the Alamiro Robledo Auditorium of the Faculty of Physical Sciences and Mathematics at our University with the presence of his family, teammates, friends and the evaluating Committee, composed of his research advisor, Dr. José Aguirre, as well as professors Dr. Claudio Faúndez and Dr. Hernán Astudillo, who, after listening to the presentation, praised the now-Master of Science for the high quality of his work, which took about 3 years.
“It was a gratifying process, but it was also difficult experimentally. I, for example, had to change the subject of my thesis. We had to forge ahead with very little, in comparison to other laboratories that reported the same,” Sebastian said, who also appreciates the support of CEFOP to assemble the Laboratory of Coherent Control of Atoms and Light (LCCAL), which is mainly oriented to observe interaction phenomena of atoms in fields.
His research advisor, Dr. José Aguirre, highlighted the work carried out by Sebastian: “It is really a joy that Sebastian completed his thesis work and we hope that in the coming months, two more students will defend their research. From the point of view of results, some years have passed and we are now seeing the fruits of the investment of time, energy and skills. The example of Sebastian’s work is precisely a message that hard work pays off.”
Sebastián Lavín is the second researcher who obtained results in this lab. In his research, he worked exclusively with atoms. “Lasers were characterized and later realized the electromagnetically-induced- transparency-related phenomenon in another sample of atoms,” Dr. Aguirre explained.
For now, Sebastian Lavin’s plans point to a continuation of his studies toward a Ph.D., which will allow him to carry out research in Australia or in Europe. He is also interested in the continuation of the LCCAL laboratory: “The idea is that an exclusive CEFOP laboratory stays equipped so that they can continue to do these kinds of experiments. In fact, there are currently 3 more experiments in execution and two master theses in development for defense,” he noted.
