Adjusting optical properties of optical thin films
TL;DR: In this paper, the authors proposed to include the thin film as a layer in a thin-film optical filter, which can provide a corresponding variation in the filter's spectral properties along a dimension that is perpendicular to its thickness.
Patent
Power laser with deflection
TL;DR: In this paper, a non-linear medium (NL1) within which a first beam of fixed direction and a second beam of orientable direction interfere with each other is considered.

Compact lighting device
TL;DR: In this paper, a compact lighting device is proposed for lighting an active matrix in a monochrome or trichromatic display device. But this device comprises a source and collimating means for delivering a lighting direction of the source along a direction, and two optical components (M1 and M2) ensuring the anamorphosis of the lighting in a direction parallel to the direction (Dy) and in adirection (Dz) perpendicular to the orientation of the direction(Dy).
Patent
Phase conjugation device
TL;DR: The phase conjugation device as mentioned in this paper includes at least one nonlinear medium and an optical focussing system producing at least two focal points within the non-linear medium, and capable of focusing light at these two points.
