Abstract

We describe a novel side-pumping configuration of the virtual-point-source diode-array-pumped Nd:YAG laser with 32 cw 10-W laser diodes. A new concept of the virtual point source and an image-relay system are proposed for the generation of a Gaussian-like pumping profile with an optically thin gain medium. A cw linearly polarized TEM00-mode, 26.5-W output was obtained at a diode pump power of 171 W. The M2 values at the x and y axes were measured to be Mx2=1.03 and My2=1.20, respectively.
