Shaping the beam space distribution of a laser diode using two types pumping optics is reported. The dependence of the output characteristics of a Nd : YAG laser on different ellipticities and collimation of the pumping beam is analyzed. The efficiency is strongly increased when the ellipticity goes to 1. The output power is 1. 13 W with the pumping power 2. 42 W, and the slope efficiency is 50%. In addition, the comparison of slope efficiency between two YAG crystals of different Nd concentrations is performed.
