Patent number: 11936157Abstract: A laser device comprises a first optical cavity comprising a first gain medium and a second optical cavity comprising a second gain medium. The first gain medium and the second gain medium generate light at respective different ranges of wavelengths. A synchronizer is optically coupled to both the first optical cavity and the second optical cavity and is configured to synchronize and mode-lock light from the first optical cavity and the second optical cavity. The laser device also includes a first optical filter and a second optical filter to filter the light from the first optical cavity and the second optical cavity respectively to output first filtered light pulses at a first predetermined range of wavelengths and second filtered light pulses at a second predetermined range of wavelengths.Type: GrantFiled: May 11, 2018Date of Patent: March 19, 2024Assignees: CAMBRIDGE ENTERPRISE LIMITED, POLITECNICO DI MILANO, FONDAZIONE INSTITUTO ITALIANO DI TECNOLOGIAInventors: Daniel Popa, Giulio Cerullo, Tullio Scopigno, Dario Polli, Andrea Ferrari

Publication number: 20240036434Abstract: Exemplary method and configuration for a frequency conversion can be provided. For example, such method and configuration can use at least one transition metal dichalcogenide (TDM) crystal (which can include one or more MoS2 crystals, which can be stacked). For example, it is possible to providing at least one radiation to the at least one TDM crystal so as to generate a resultant radiation. Resultant information can be generated by measuring difference frequency and a second harmonic generation (SHG) from the resultant radiation provided from the TDM crystal. The frequency conversion can be obtained or achieved by providing a measurement of a SHG coherence length based on the resultant information.Type: ApplicationFiled: July 27, 2023Publication date: February 1, 2024Inventors: XINYI XU, CHIARA TROVATELLO, FABIAN MOOSHAMMER, YINMING SHAO, SHUVAIT ZHANG, KAIYUAN YAO, DMITRI N.

Patent number: 11346719Abstract: A Fourier-transform hyperspectral imaging system may include an optical imaging system configured to produce an image of an object, and an adjustable birefringent common-path interferometer module comprising a movable birefringent element and configured to produce interfering replicas of an input radiation which are delayed from each other by a phase delay adjustable by the moving birefringent element. The interferometer module may be configured to produce collinear replicas for entering optical rays parallel to said optical axis. The hyperspectral imaging system further comprises a two-dimensional light detector configured to receive the replicas and provide digital images of the object depending on said adjustable phase delay. The system also includes an analysis device configured to perform a Fourier Transform of the digital images to obtain a hyperspectral representation of the object.Type: GrantFiled: July 25, 2019Date of Patent: May 31, 2022Assignees: POLITECNICO DI MILANO, CONSIGLIO NAZIONALE DELLE RICERCHEInventors: Cristian Angelo Manzoni, Giulio Cerullo, Dario Polli, Antonio Perri, Fabrizio Preda, Gianluca Valentini, Andrea Bassi
