Tunable, continuous wave, thulium-doped, solid state laser
This patent describes a room-temperature solid state laser. It comprises means for emitting a CW pump beam at a preselected wavelength; a laser cavity defined by first and second reflective elements opposing each other on a common axis to form a reflective path therebetween; a laser crystal disposed in the laser cavity, the laser crystal having a host material doped with an amount of thulium activator ions sufficient to produce a CW laser emission in the range of a plurality of wavelengths determined by Stark components n the {sup 3}F{sub 4} to {sup 3}H{sub 6} laser transition in the thulium activator ions when the laser crystal is pumped by the CW pump beam; and means disposed in the laser cavity between the laser crystal and the second reflective element for tuning the CW laser emission to any of the plurality of wavelengths within the range between approximately 1.86 microns and approximately 2.14 microns.
