  • Patent number: 10795169
    Abstract: An illuminator optical system combines, homogenizes, and shapes light spatially and angularly from one or more high power fiber coupled lasers. It may include a multichannel fiber cable, collimation and beam shaping optics, a multiple lens array (e.g., fly's eye lens array), and an objective lens. The multichannel fiber collects the light from the high power fiber coupled lasers and produces an aligned array of one or more optical fibers at the output of the cable. The light output from the cable is collimated and relayed to a multiple lens array that spatially divides and shapes the light into an array of beams. The objective lens homogenizes the light by collimating and overlapping the beams into a uniform top hat irradiance distribution in at least one dimension, resulting in the illumination pattern having the required spatial size and desired angular distribution at the illumination plane.

  • Patent number: 10768361
    Abstract: A monitoring system monitors changes in an index of refraction of the grating over a time interval that includes the period of time. The monitoring system includes a light source assembly, a probing assembly, a power meter (e.g., a diffraction and/or a transmittance power meter), and a controller. The light source assembly emits a probe beam. The scanning assembly scans the probe beam over an area of the grating. The power meter measures power of a portion of the probe beam that interacts (e.g., is transmitted by or diffracted from) with the area of the grating. The controller determines changes in grating parameters (may be as a function of time) for the grating being formed based in part on measured power readings over the time interval.
