Abstract : A room temperature solid state laser for producing a laser emission at a wavelength of substantially 2 microns is disclosed. In a preferred embodiment, the laser comprises: a laser crystal having a host crystal material doped with an effective percent concentration of CR3+ sensitizer ions and with an effective percent concentration of Tm3+ activator ions; and a flashpump for exciting the crystal to produce a laser emission at substantially 2 microns at a slope efficiency of at least 2 percent.
