Molecular resonance stimulated by low intensity laser light

摘要

This invention provides an apparatus comprising a laser diode (2) whose wavelength is modulated by an amplitude modulator (1). The laser output is collimated by a lens (3) and passed through an optical element (4) which contains two diffraction gratings spaced by a refractive element. The resulting output contains an interference pattern which can be selected and controlled to interact with chosen molecules so as to induce molecular resonance.
