ABSTRACT:
A solid state tunable laser resonator having a laser element, an excitation light source for outputting a pumping light, and elements for selecting a wavelength of the pumping light and directing the wavelength of the pumping light onto the laser element at a first point thereof on a first axis substantially parallel to an axis of oscillation light emitted by the laser element. The laser resonator may also include elements for directing the pumping light onto the laser element at a second additional point thereof. The laser resonator can be used as a laser light source having a wide tunable range with a narrow line width.
