Abstract The paper presents investigations of a free space optical transmitter operating with quantum cascade lasers. The main goal of the research was to determine influence of lasers driver parameters on an optical data link performance. Using some commercial driving devices, the laser pulse limitations of power, repetition rate and time duration have been observed. In the paper, the preliminary results of the designed laser driver are described. The driver was developed at the Institute of Optoelectronics, MUT in cooperation with scientists from the Faculty Electrical Engineering, WUT. It is characterized by high current efficiency, high pulse repetition rate, and compact construction. Additionally, the driver also includes a controller of Peltier modules

Abstract The article presents an overview of the work on quantum cascade lasers application in free space optical systems (Free Space Optics - FSO). There are discussed the main issues of the open-space laser communications and their practical construction. Comparative analyses of each FSO technology were performed. Brief description of quantum cascade (QC) lasers and some developments related to the use of these lasers in optical data link are also presented. In summary, the constructed models of FSO links with QC lasers are characterized.
