The Division of Laser and Atomic Research and Development was founded to perform basic research in the field of laser and atomic physics. Using this knowledge and experience, the Division has grown quite large, with the primary task of expanding results from basic research into applied research and development. The current development activities in the Division are primarily oriented to the development of optical and optoelectronics devices, and sometimes laser-based devices. Starting from the results of applied research, we proceed to development. Development occurs simultaneously in the fields of optical systems design, thin-film optical multilayers, optoelectronics devices application and optomechanical CAD. The newest breakthrough has been in the development of devices for photodynamic diagnostics and tumor therapy. The final results of our extended development activities can be found by browsing through our products: medical and defense.


The Division conducts research on optical thin-film systems and imaging and non-imaging optics, as well as in the fields of blind signal processing and multispectral data analysis.


The Division has extensive experience in the development and manufacture of medical and military devices.


The Division emerged from the work of Professor Branimir Marković, one of the cofounders of the Ruđer Bošković Institute, and the Laboratory for Nuclear and Atomic Research. In the 1970s, the Laboratory became an autonomous division within the Institute. From research in the field of atomic physics and the structure of atomic levels through the development of the first laser in the region and various laser applications, the Division veered into the field of photonics. In the past 20 years, several research projects have been conducted in area of imaging and non-imaging optics and optical thin-film systems. Of special significance is recent work in biophotonics, with particular emphasis on photodynamic processes in malignant skin tissue. In this area, applied algorithms for digital image processing are being developed that provide clear discrimination between healthy and tumor tissue.

The Division has received accolades and awards for innovations in photonic applications. In September 2006, the Division established a system for quality control according to standard ISO 9001:2000 and received certification in January 2007.

Department LAIR conducts intensive research in the field of photodynamic diagnosis and therapy. Several modern devices for application of light in medicine have been developed in Division. The results of our efforts are diagnostic and therapeutic devices MediLED. MediLED devices are based on advanced light source technology, light emitting diode - LED, which allows to emit narrow band of incoherent light.

Our devices can be used in following fields:

  • photodynamic diagnostics (PDD), e.g. detection of some dermatological disorders
  • photodynamic therapy (PDT), e.g. treatment of certain dermatological conditions using light and photosensitizing agent
  • biostimulation, e.g. reducing pain and improving wound healing
  • cosmetics, e.g. depilation using combination of light and photosensitizing agent

We developed several MediLED devices, for various applications:

  • MediLED 4 PDD & PDT. An advanced computer controlled apparatus for clinical application.
  • MediLED Vio, Thera and TheraCont. Compact and portable devices for ambulatory application.
  • MediLED 5. Designed for large area treatment.
