Patent ID: 7991028

Claim:
A laser system for emitting continuous wave output within a preselected range of wavelengths, comprising: a solid-state lasing element, doped with an active ion that is pumped with a first wavelength and generating emission with a second wavelength in response to the pumping light; a light optimizing solid state optical laser medium configured to optimize output light emitted by the lasing medium, said optimizing laser medium being close-coupled to the lasing medium, said frequency conversion arrangement generating output in a third wavelength; a stable resonator defining a laser resonator cavity and housing a solid-state lasant, at least two highly reflective end elements, and an output coupler reflective element arranged to form a reflective path defining said laser resonator cavity there between, said resonator being configured to receive the light beam in the third wavelength and produce a solid-state laser optical output in a 650-1170 nanometers range; wherein said solid state lasing element is selected from a group consisting of neodymium-doped solid-state crystalline host materials; wherein said titanium-doped sapphire crystal comprises an exit face cut at a Brewster's angle; wherein said resonator comprises a tuning element configured to select wavelength output of said solid-state lasant; and further comprising at least one thermo-electric controller.
