Title: The Innovative Contributions of Inventor Keming Du
Introduction
Keming Du, an accomplished inventor based in Aachen, Germany, has made significant strides in the field of optical engineering. With a total of 14 patents to his name, his innovations aim to advance laser technology and its applications in various industries.
Latest Patents
Among his most recent inventions is an optical assembly designed for enlarging spectral bandwidths and reducing ultrashort pulses. This optical arrangement employs nonlinear self-phase modulation within a multipass cell, enabling a laser beam with ultrashort pulses to traverse the nonlinear medium multiple times. A shaping optical unit is utilized to transform the laser beam into an astigmatic beam, which is then effectively coupled into the multipass cell.
Another noteworthy patent from Du includes a resonator system featuring at least two folding elements. This system is vital for folding the beam path while simultaneously restricting the divergence angle of the radiation. The innovative design relies on reflection from the surfaces of the folding elements, with the beam axis positioned at an angle relative to the surface normal that is critical for total reflection yet less than the combined angles of the critical angle and the divergence angle.
