This patent application discloses a room-temperature solid state laser for producing a laser emission at a wavelength of substantially 2.09 microns. In a preferred embodiment, the laser includes a laser cavity defined by first and second reflective elements opposing each other on a common axis to form a path therebetween a laser crystal disposed in the laser cavity, the laser crystal having a host material capable of accepting Cr3 sensitizer ions, Tm3 sensitizer ions and Ho3 activator ions effective amounts of Cr3 sensitizer ions, Tm3 sensitizer ions and Ho3 activator ions dispersed within the host material and means for exciting the laser crystal to produce a laser emission at substantially 2.09 microns with slope efficiency of at least 4, and preferably of at least 5.
