Design and realization of a conventional carbon dioxide laser was performed.
Gas composition and gas pressure effects on laser output power were studied. Effects
of input electrical power and current on laser power were also investigated. Beam
profiling of the laser beam was performed by pinhole method. Laser beam
parameters like beam divergence, beam propagation factor were measured. These
properties were extracted from focusing a laser beam in near field and performing a
number of cuts across the beam cross-section and measuring the beam diameter at
these points. Diameter measurements were obtained by knife edge method. Laser
beam parameters were obtained for three different power laser beams in two axes
across the beam. Found parameters were compared with regard to beam power and
beam cross-section axis. Also possibility of using the obtained laser beam in material
processing was investigated.
