Who We Are

Vision and Values

The Head of the Laser Spectroscopy and Optics (LSO) group is Dr. Angela Staicu.

The group was founded, as Laser Spectroscopy Group (LSG), in 1975 by Prof. Mihail Lucian Pascu, within the Institute of Physics – Bucharest (IFB) which belonged, at the time, to the Romanian Academy. It functioned between 1975 and 1977 as part of IFB, between 1977 and 1996 within the Institute of Physics and Technology of Radiation Devices (IFTAR) - Laser Department and from 1996 to-date as part of the National.

In 2018 LSG took over the Laser Interferometry & Applications (ILA) Group of INFLPR which was founded in 1982 by Dr. Dan Apostol. The new group is denominated currently Laser Spectroscopy and Optics (LSO) Group and includes 17 scientists out of whom – at the moment - 14 PhD in physics, one PhD student, one assistant research scientist and one technician.

What We Do

The scientific activity developed by the group includes:

  • research on development of tunable dye lasers and tunable semiconductor lasers
  • basic research on laser active media: chaotic emission of laser beams, tunable droplet lasers having milli-, micro- and nanometer diameters
  • research and development of laser medical equipment
  • basic research on atomic, molecular and bio-molecular spectroscopy
  • research and development of laser equipment to monitor environment (air, water, soil, biosphere) pollution
  • basic research on complex molecules related to environment pollution
  • basic research on laser beam interaction with tissues, cells and medicines
  • laser based methods to develop new medicines for use to fight the multiple drug resistance (MDR) acquired by bacteria and developed by tumor tissues.
  • unresonant and resonant interaction of the laser beams with micro- and nano-droplets
  • optofluidics related to nanosciences
  • specular reflection and speckle interferometry
  • holography
  • diffractive optics
  • adaptive optics
  • scatterometry
  • measurement of lengths and shapes, at wavelengths in the visible
  • optical and spectroscopic applications of laser beams at THz frequencies
  • profilometry (white light and stylus)
  • optical microscopy
  • measurement of displacement, shape, vibration
  • THz imaging
  • THz time-domain spectroscopy
  • laser ablation
  • Our collaborations


    Within International cooperation projects, the group received and continues receiving scientists from abroad to work within it, particularly on the topics related to the laser physics and laser methods used to develop new medicines and conceived to fight multiple drug resistance of bacteria and cancer tumors.
