14 December 2010Measurement of optical beam for free space optical link
The paper deals with the modeling and measuring of laser beams parameters. Utilization of laser beams is intended for
example in free space optical links with the range about several hundred meters. By the help of submitted laboratory
works the students acquaint with basic parameters and basic characteristics of laser beams, modeling of laser beams, and
with suitable methods used for improvement of transmission reliability.
The laboratory exercise will be aimed on the measurement of energy and geometric properties of laser beam as well as
on the determination of wave properties. We will focus on the mentioned quantities from the sight of total irradiated
optical power, the distribution of optical intensity in laser beam profile and half width of energy equivalent beam. The
spectral characteristics of optical beam and spectral linewidth will be the part of the laboratory exercise.
The contribution has pedagogic character and it is closely adherent to the research realized at our institute. Generally we
are focused on the research of optical wireless links in atmosphere so the solved problem is from the area of current
problems of research.
