چکیده انگلیسی
A pulsed doubly resonant LiB3O5 (LBO) optical parametric oscillator design (OPO) at degenerate case pumped with a frequency doubled Q-switched Nd: YAG laser was built-up. The LBO crystal was designed for collinear phasematching. The threshold power density at degenerate case was 141.4â¯MW/cm2. The linewidth of the amplified output at degenerate case due to both signal and idler beams was found to be 10â¯ns. The effect of crystal rotation in the horizontal plane on the output energy per pulse of both signal and idler were studied. The OPO maximum output energy per pulse at degeneracy was assessed, it was 54â¯Î¼J for 20â¯mJ pumping energy at optimum phasematching angle θpm=11.2°. The theoretical calculations that describe the output energy per pulse at different input pumping energy for the LBO-OPO linear cavity are numerically simulated and compared with the experimental results as well as conversion efficiency calculations at optimum phasematching.
