Dynamically stable operation with joined stability zones of a linearly polarized resonator is shown for a
laser containing two diode side-pumped Nd:YAG rods. The unpolarized resonator generated 115W of
output. When polarized by a Brewster plate, it reached 100.5W of output power at a beam quality
M2 < 2. Best measured beam quality was of 1.1 and 1.3 in the x and y directions respectively, with
76W of 95% polarized output. The output power achieved is, to our knowledge, the highest reported
for continuous polarized, fundamental-mode lasers using standard side-pumped Nd:YAG modules.
