Abstract:
An optical system and method are presented for use in a multi-photon microscope. The system comprises an imaging lens arrangement, and a pulse manipulator arrangement. The pulse manipulator arrangement comprises a temporal pulse manipulator unit which is accommodated in an optical path of an input pulse of an initial profile, and is configured to affect trajectories of light components of the input pulse impinging thereon so as to direct the light components towards an optical axis of the lens arrangement along different optical paths, said temporal light manipulator unit being accommodated in a front focal plane of the imaging lens arrangement, thereby enabling to restore the input pulse profile at an imaging plane.
Abstract:
A method and system(10) are presented for producing exciting radiation (P’) to be used in producing an output coherent anti-stokes Raman scattering (CARS) signal of a medium (12). An input spectral phase coherent optical pulse (P), carrying a pump, a Stokes and a probe photon, is optically processed by adjusting spectral phase and polarization of wavelength components of the input pulse to produce a unitary optical exciting pulse (P’) that carries the pump photon, the Stokes photon and multiple probe photons and is capable of inducing interference between contributions from at least some of vibrational levels in the CARS signal.

Abstract:
A method or apparatus for wireless transferring energy between a source coil and a drain coil, comprises selling an initial resonant frequency of the source coil as a first condition; setting the source coil and said drain coil in positions relative to each other to define an initial coupling coefficient therebetween, so that the initial coupling coefficient comprises a second condition; and adiabatically changing one or both of the conditions while pumping energy into the source coil. The source coil energy is transferred to the drain coil over the course of the adiabatic change.
Abstract:
The microscope (10) includes such main constructional parts as a light source assembly (12); and an optical system (16) configured according to the invention, and in the present example of microscope (generally imaging) system configuration includes also a detection unit (14) (shown in the figure in 5 dashed lines). The detection unit (14) may be configured to define an array of image pixels (e.g. CCD), may be configured for intensified or not intensified light detection, as well as for gated or not-gated light detection. It should be understood that the light source, as well as the detector, may or may not be accommodated in the same housing (15) enclosing the optical path of an input pulse of an initial profile, and system (16). For example, the light source and/or detector may be accommodated outside the housing (15) and light may be guided towards and/or away from a sample S via light guiding means (either in free space or in optical fibers).
