four W ended up computed using the symmetric optical resonator. Although, with the asymmetric optical resonator, highest basic method solar laser collection effectiveness of sixteen.one W/m2 and brightness determine of advantage of 37.three W were being numerically realized. The asymmetric resonator offered a TEM00-mode laser electric power decreased when compared to the 1 obtained utilizing the symmetric resonator; however, a collimated laser beam was extracted from your asymmetric resonator, contrary to the divergent TEM00-mode laser beam supplied by the symmetric resonator. Even so, employing the two optical resonators, the TEM00-mode Ce:Nd:YAG photo voltaic laser energy and beam brightness determine of benefit had been significantly higher compared to numerical values received with the past Nd:YAG solar laser considering precisely the same Major concentrator.
