The use of a dynamically stable telescopic cavity to compress the cavity length of intra-cavity doubled, TEM₀₀ mode, optically-pumped semiconductor lasers (OPSL's) is evaluated. We find that the cavity length may be adjusted (approximately) between the Rayleigh lengths of the mode sizes on the end mirrors without sacrificing output power or dynamic stability. Consequently, for a 10 W OPSL, the length may be scaled between about 1 and 100 cm. In addition, we calculate that in all respects, the cavity stability range and misalignment sensitivity maintain practical values to about 1 cm cavity length. These results are applied to demonstrate OPSL's producing TEM₀₀ mode outputs of 11.5 and 7.3 W at 531 and 486 nm with resonator footprints as small as 15 mm.
