Abstract: (1585 Views)
In this paper design and fabrication of an Yb-doped fiber laser at 1064nm along with a Fabry-Perot bow tie cavity inside the fiber laser cavity is presented. The circulating power inside the laser cavity is enhanced by the intracavity passive locking technique from 5.1W in the main cavity to 52W in the Fabry-Perot cavity. By placing an LBO crystal within this resonant enhancement cavity, efficiency of the second harmonic of laser in continuous regime is increased from 0.05% to 25% that result to 1.3W light at 532nm. Thus, the efficiency of the second harmonic generation of continuous light in the LBO crystal is increased about 486 times.
