A new, highly efficient, scalable technique for cw high-power diode-array side pumping of gain media has been developed. The use of simple all-reflective optics permits diode emission collection efficiencies of [gt]95%. We have achieved a cw TEM[sub 00] mode output ([ital M][sup 2][lt]1.1) of 13.1 W at 1.06 [mu]m from a Nd:YAG rod pumped with 60 W of laser-diode output (808 nm), representing 22% conversion efficiency (29% conversion of absorbed pump power). Numerical simulations and experimental results indicate that good thermal management results in thermally induced aberrations of [lt][lambda]/8 across the rod.
