Abstract: (1630 Views)
In this paper, different ways to get uniform and increased absorption flux of Nd:YAG laser with single-side diode pumping geometry were investigated. In the first suggestion, the slab laser is coated from three sides and use an additional reflector at the entrance to the cavity with a slit for injection of the pumping radiation. In the other suggestion, we designed the optimal dual composition of divergent arrays micro lens and placed in front of the diode that by increasing the divergence angle makes the uniformity of pumping. The results of each simulation are compared and analyzed.
Keywords: Absorption Flux, Single Side Pump, Nd:YAG Laser, Divergent Micro Lens, Uniformity of Pumping.
