A tunable ytterbium-doped solid-state laser has a laser cavity defined a pair of mirrors, a laser medium positioned in this cavity, means for pumping the laser medium, and means for tuning the output of this laser medium to a selected wavelength within a wavelength range. The laser medium has a host material doped with enough ytterbium ions to produce a longitudinal mode laser emission when the laser medium is pumped. In a most preferred embodiment, the laser emission is frequency-doubled and tuned to a wavelength corresponding to a Fraunhoffer line in the solar spectrum. Author
