    • Fiber laser system for the detection of trace gas 

      Valiunas, Jonas Kestutis (2017)
      The research presented in this thesis is on the development of a trace gas detection system based on intracavity absorption spectroscopy (ICAS). The developed system was capable of detecting nitrous oxide (N2O) and acetylene ...

    • Tunable high-power fiber laser and its application to produce Brillouin fiber lasers 

      Valiunas, Jonas Kestutis (2012-11-10)
      A tunable continuous wave single-longitudinal-mode fiber laser is proposed and developed. A saturable absorber, as well as, an all-fiber Fabry-Perot filter was used in the laser cavity to reduce mode-hopping. The laser ...
