An Optical and Thermal Study of Laser Production by a Parabolic Dish Solar Concentrator in Ouargla Region

Abstract

In this paper, based on the simulation, we concentrate the solar radiation in Ouargla region in Algeria for laser production. The parameters location of this region were the longitude is L=5.24, latitude is φ=31.57, and the height above the sea level is Z=141 m. To do so, we use a reflective dish with two different diameters in a summer day and winter day as well. The laser production is achieved by side-pumping of three lasers namely YAG:Nd rod , YAG:Nd plate and GSGG:Nd:Cr rod. To get a suitable temperature for the laser, we use a refrigeration system and a solar spectrum filter. We obtained a 7.84Mw/m² concentred radiation and recorded an inpower of 955.5 W and anoutpower of the laser equal to 46.43 W.
