A diode-pumped solid-state laser including a short wavelength (e.g., blue,
violet, or UV) semiconductor laser that pumps an absorption transition in
a rare-earth-doped material. Responsive to this pumping, the rare-earth
active ion directly emits laser radiation. A number of different
wavelength outputs, including short wavelengths, are achievable dependent
upon the material and the pump wavelength. The gain medium may include an
active ion selected from Er.sup.3+ Sm.sup.3+, Eu.sup.3+, Tb.sup.3+,
Dy.sup.3+, Tm.sup.3+, Ho.sup.3+, and Pr.sup.3+. A laser diode pump source
has a wavelength in the range of about 365 nm to 480 nm to excite a laser
emission in the range of 370 to 800 nm. The laser diode pump source may
comprise a GaN-based semiconductor. In some embodiments, the laser diode
pump source supplies a pump beam in a range of 370 380 nm, 400 415 nm,
435 445 nm, or 468 478 nm.
