  • Patent number: 11944448
    Abstract: A system and method for adaptive illumination, the imaging system comprising an excitation source having a modulator, which generates a pulse intensity pattern having a first wavelength when the excitation source receives a modulation pattern. The modulation pattern is a data sequence of a structural image of a sample. An amplifier of the imaging system is configured to receive and amplify the pulse intensity pattern from the modulator. A frequency shift mechanism of the imaging system shifts the first wavelength of the pulse intensity pattern to a second wavelength. A laser scanning microscope of the imaging system receives the pulse intensity pattern having the second wavelength.

  • Publication number: 20230307882
    Abstract: A laser head for a high power fiber laser system has a 5 to 10 mm high housing which is provided with a bottom. The housing encloses an input collimator assembly which collimates a single mode pump light at a fundamental frequency and maximum power of 2 kW. The housing further encases a multi-cascaded nonlinear frequency converter receiving the collimated pump light so as to convert the fundamental frequency into a higher harmonic thereof, wherein converted light at the higher frequency has a maximum power of 1 kW. Enclosed in the housing are electronic and light guiding optical components mounted in the housing. The bottom of the housing is an electro-optical printed circuit board (EO PCB) which directly supports the input collimator assembly, multi-cascaded nonlinear frequency converter, electronic and optical components at respective designated locations.
