Theoretical Study of the Effects Type of Host’s Crystal on the Lasing Output of High – Power Thin –Disk Laser
Main Article Content
Abstract
Ytterbium-doped (Y2O3), (Sc2O3) and (YAG) crystals are very important for high-power thindisk lasers. These lasers have shown their ability to operate quasi-three-level materials with high
efficiency as well as high thermal conductivity ratio for crystalline hosts. All these reasons have
required studying this type of laser. In the present work, the analytical solution was found for the
equation of laser output power, pumping threshold power, and efficiency of a quasi-three-level
thin disk laser. The numerical solution of these equations was also found through the Matlab
program at the fundamental transverse mode, at a temperature of 299K0
and with high pumping
capabilities in order to know the effect of the type of crystal host (YAG, Sc2O3,Lu2O3) on the laser
production of this design and thermal effect when operating continuously. We found out that the
crystal host (Lu2O3) was the best type of these hosts in obtaining the highest laser output power
and efficiency at all values of pumping power
