  • Real-time chemical sensing using stimulated Raman scattering in nanofibers
    Patent number: 11204325
    Abstract: A system includes a laser (1) operative to emit a light beam, a beam splitter (2) arranged to split the light beam into a first beam and a second beam, the first beam being directed to a nonlinear converter (8) that generates a signal beam having a Stokes-shifted wavelength, a recombiner (9) arranged to recombine the signal beam with the second beam to form a recombined beam which is directed to a tapered optical fiber (5) located within a material to be monitored, and a detector (7) arranged to detect light emitted by the tapered optical fiber (5) and which uses stimulated Raman spectroscopy to detect a chemical in the material.

  • Optical frequency converter for non-polarized light
    Patent number: 7463410
    Abstract: Optical apparatus including an optical frequency conversion device, pumped by a non-polarized light beam. The apparatus may include a pump incident side, such as an optical fiber emitting non-polarized light beam, a polarization beam splitter to split the incident beam into two polarized beams, beam forming optics to shape the beams and rotate their polarization as required and couple them into the conversion device, and an optical frequency conversion device to convert the wavelength of both beams into a new wavelength.
