Claim Text:
1. A triply-optically-pumped atomic laser (TOPAL), comprising: an optical cavity that has a resonance at a predetermined wavelength within a range from ˜230 nm to ˜370 nm; a gain medium within said optical cavity, said gain medium comprising a mixture of at least one buffer gas and an atomic vapor; wherein said gain medium has at least one ultraviolet (UV), parity allowed, electric dipole transition in said range that terminates on the ground level of said atomic vapor, wherein said predetermined wavelength is resonant with said UV, parity allowed, electric dipole transition, wherein said buffer gas collisionally rapidly transfers pump-excited electron population between excited n an oven configured to maintain said gain medium at a predetermined temperature; a continuous wave (CW) first pump laser configured for emitting a first pump beam having a wavelength λ a CW second pump laser configured for emitting a second pump beam having a wavelength λ a CW third pump laser configured for emitting a third pump beam having a wavelength λ means for directing said first pump beam, said second pump beam and said third pump beam into said gain medium.
