Apparatus is disclosed for upconverting a laser spanning the near IR region into the near UV region. An alkali halide, for example, NaI, is photodissociated via a coherent or an incoherent pump source, for example, and ArF excimer laser or an ArF excimer flashlamp. A near IR laser, for example, a CO2 laser, is then focused into a cell containing the photodissociated Na (Na*), thereby producing anti-Stokes Raman emission in the near UV region. |
