Abstract : 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 Cr(3+) sensitizer ions, Tm(3+) sensitizer ions and Ho(3+) activator ions; effective amounts of Cr(3+) sensitizer ions, Tm(3+) sensitizer ions and Ho(3+) 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%.
