Description of the Study Program

Lasers and Optical Spectroscopy constitute a foundation of several branches of today's modern technology. Particularly by developing the fields of telecommunication, optoelectronics, microelectronics and nanotechnology. Laser technology in conjuncture with vacuum and plasma technologies is applied for surface treatment of polymer materials and metals. Also it provides the means to compare the material quality to benchmarks as used in metal industry. The students will gain experience in ultrasensitive optical spectroscopy (CRDS, CEAS and LIBS) ranging from the vacuum UV to near-IR region. This puts our graduates in advantageous position for further work in fields of the detection of trace elements, radicals and molecules in the environment, in medicine, criminology, civil defense and the detection of drugs, explosive and narcotic substances. Currently a great attention is given to laser spectroscopy for purposes of monitoring the purity of the environment.

In the presented study program, the research focuses on the generation of laser radiation and the application of lasers in the following: the study of nonlinear properties of materials (microstructure optical fibers), exploring new aspects of holography and interferometry, and optical spectroscopy from the vacuum UV to the near IR region. We use lasers with pulse lengths ranging from ns to fs.

The Laser spark generation is studied using a time-resolved Emission Spectroscopy (LIBS). The experimental focus is put on the development of new methods for the ultra-high resolution laser absorption spectroscopy using resonators (CRDS, CEAS, etc) that allow for the detection of traces of atoms and molecules in the environment. We carry out applied research in developing new DPSS lasers of medium power, and also the tunable VECSEL lasers in the near infrared region. LIBS is used as an alternative technique of element analysis in medicine, archeology, materials engineering, ecology and geology. In connection with the thermonuclear fusion (ITER) we participate on the optical diagnostics of plasma interaction with the surface of the reactor chamber.

This study program is closely cooperating with the International Laser Center and FU SAV. The international recognition of our work provides oportunities for our students to apply for internships and further studies at the universities of Dijon, Lille, Strasbourg, Grenoble, Marseille, Brussels, Linz, Prague and others. 

What to Expect

The core of the program consists of subjects focused on laser physics and optical spectroscopy (main two blocks of the study program), and experimental physics (two blocks of compulsory and elective subjects) and application of knowledge in other scientific disciplines(block practical exercises and corresponding lectures).

In addition, the student has a wide choice of modules in this program, but also from other study programmes (eg. Numerical computation, mathematics, history of physics and humanities). Lectures are chosen in accord with the interests of the students and recommendations of the supervisor of their Mater thesis.

Master's Thesis. The thesis address experimental or theoretical tasks in the field of optics, lasers and optical spectroscopy. Their content is focused primarily on issues related to the generation of laser radiation, nonlinear phenomena and also the use of lasers for optical spectroscopy. Experimental works are supplemented by specific simulations. The theoretically oriented projects primarily deal with modeling of complex physical phenomena arising from the interaction of radiation with matter under extreme conditions.

The thesis reflects the students ability to independently acquire theoretical and practical knowledge based on the current state of the research field and also to apply them in a prolific manner. The supervision of a master thesis also relays on staying in contact with experts from the International Laser Center, Research Institutes and cooperating universities abroad, where most of students spend one semester (or more) on ERASMUS or other forms of cooperation. These experts, together with teachers from Comenius University creates experienced team of tutors and supervisors for diploma theses.

Here are some examples of diploma thesis of our graduated students:

Graduates' Career Opportunities

The most important knowledge, abilities and skills that graduate learns: 

  • the ability to solve common problems of modern physical optics both independently or in a team, particularly in the field of laser physics, optical information processing and optical spectroscopy.
  • the ability to implement advanced optical principles and methods in other disciplines, to create and use computer models of physical phenomena and processes, and to responsibly use modern optical systems and equipment
  • will be able to build and use a variety of optical equipment required for optical diagnosis, or for the use of lasers in various fields of science (quantum electronics and optics, plasma physics, physics of the environment, etc. )
  • will be able to apply standard software for the statistical data processing, spreadsheets, word processing, hypertext, graphical presentation and publication of results.
  • will be able to work with the acquisition systems in order to collect data from experimental devices to PC and to create computer programs to control experimental systems and interpret the results. 

The knowledge and competencies obtained allow the graduate to apply them in conducting basic research at universities, Institutes, International Laser Center and other research centers at home and abroad). The experience gained in dealing with international and domestic projects during the study, enable the students to integrate into interdisciplinary teams of both basic and applied research.
