This is the first report of a recombination laser that has been produced in laser-vaporized target material. Input-laser-pulse energies as low as 0.5 mJ at 1.06 μm and 5 mJ at 10.6 μm have resulted in laser oscillation in Cd i at 1.40, 1.43, 1.45, and 1.64 μm in ≈1-cm-radius cadmium plasmas. This laser appears to have the potential for high efficiency. In addition, scaling of this plasma-recombination process to higher-ionization stages should yield short-wavelength lasers.
