Abstract:

A laser system and method for producing a laser emission at a wavelength of substantially 2.8 microns is disclosed. In a preferred embodiment of the invention, the laser system comprises a crystal having a host material doped with erbium a laser cavity defined by first and second reflective elements at opposing ends of the crystal to form a reflective path therebetween and resonant pumping means for directly pumping the 4I112 upper laser state of the erbium with a pump beam at a preselected wavelength to cause the erbium-doped crystal to produce a laser emission corresponding to the 4I 112 4I 132 laser transition having a wavelength of substantially 2.8 microns, a portion of the laser emission at substantially 2.8 microns being outputted from one of the first and second reflective elements.
