    摘要: According to one embodiment of the present invention, identifying a molecule of a sample includes illuminating the sample with a preparation light beam, where the preparation light beam can initiate a substantially maximized coherence of a target molecule to yield a molecular signature corresponding to the target molecule. The sample is illuminated with a probe light beam, where the probe light beam can scatter radiation from the sample. Radiation scattered from the sample is detected, and whether the radiation exhibits the molecular signature is determined. The target molecule is identified in accordance with the determination of whether the radiation exhibits the molecular signature.

    摘要: A method and system provide coherent anti-Stokes Raman spectroscopy. In an embodiment, the system includes a detection system for measuring coherent anti-Stokes Raman signals of a sample. The system includes a first light pulse and a second light pulse. The first light pulse and the second light pulse are operable to initiate coherent vibration in the sample. The system also includes a third light pulse. The third light pulse is a probe pulse that is operable to produce scattered radiation from the sample. In addition, the system includes a spectral filter. The spectral filter shapes the probe pulse. The system further includes a detector to record the spectrum of the scattered radiation.

    摘要: A downhole thermoacoustic device comprises a heater with a terminal chamber, connected to a source or radiator of acoustic oscillation, including a hollow housing having mounted therein a longitudinal shaft carrying coils with cores in the form of a plurality of flat rings of a magnetostrictive material, operable as the active elements adapted to generate acoustic oscillation. Accommodated intermediate the coils is a member for focusing the acoustic field, in the form of a sleeve, while the longitudinal shaft carries a tube-shaped reflector of acoustic oscillation internally of the core of each coil. The top and bottom portions of the hollow housing of the radiator of acoustic oscillation have mounted therein damping elements including sleeves of a resilient material, while a heat-insulating member including a sleeve with a fluted surface is provided intermediate the terminal chamber of the heater and the hollow housing of the radiator.
