The absorption on the potassium D₂ line, output laser characteristics, and Raman scattering in potassium vapor are discussed. The spectral full width at half maximum (FWHM) of the D₂ absorption line was much greater than predicted values for pressure broadening due to the high number density of potassium atoms and the long path length. At 320 C and 0 torr of helium, the FWHM was 765 GHz. At 100 torr it was 968 GHz. At 200 torr it was 1.12 THz. The analyzed potassium laser output characteristics include the temporal dynamics of the laser cavity, the instantaneous energy efficiencies, and the spin-orbit recycling rates. At 320 C with 2500 torr of helium, a potassium laser with 1.53 MW\/cm  peak intensity and 8.25% slope efficiency was demonstrated. At 320 C and 0 torr of helium, stimulated electronic Raman scattering occurred in the potassium heat pipe. First and second order Stokes and anti-Stokes lines were visible with energy differences identical to the spin-orbit splitting of potassium. \u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Edward J.
