"We report on a unique implementation of a dual 4-f paired-gratings spectral filtering of a femtosecond (fs) laser to Atlas tag pendant realize high contrast coherent anti-Stokes Raman scattering (CARS) microscopy and high quality multiphoton microscopy on the same platform for label-free biomolecular imaging. The 4-f gratings filtering enables readily conversion of the 100 fs laser pulse trains into transform-limited 1 picosecond (ps) pulses in the spectral range of 700-1600 nm for CARS imaging," scientists in Singapore, Singapore report.

"Compared with fs-CARS microscopy, our ps-CARS imaging Tiffany Cushion Two-row bracelet yields an approximately tenfold improvement in spectral resolution, while a twofold improvement in nonresonant background suppression. High quality second-harmonic generation and two-photon excitation fluorescence imaging can also be acquired in tandem when swapping the 4-f grating filtering from the ps mode to fs mode," wrote F.K. Lu and colleagues, Singapore National University.The researchers concluded: "We demonstrate this multimodal nonlinear optical microscopy technique by imaging 465 nm polystyrene beads in water and animal liver tissue."Lu and colleagues published their study in Applied Physics Letters (Integrated coherent anti-Stokes Raman scattering and multiphoton microscopy for biomolecular imaging using spectral filtering of a femtosecond laser. Applied Physics Letters, 2010;96(13):33701).For more information, contact F.K.

According to recent research published in the journal Atmospheric Chemistry and Physics, "A critical module of air quality models is the photochemical mechanism. In this study, the impact of the Tiffany 1837 Toggle bracelet three photochemical mechanisms (CB4, CB05, SAPRC-99) on the Eta-Community Multiscale Air Quality (CMAQ) model's forecast performance for O-3, and its related precursors has been assessed over the eastern United States with observations obtained by aircraft (NOAA P-3 and NASA DC-8) flights, ship and two surface networks (AIRNow and AIRMAP) during the 2004 International Consortium for Atmospheric Research on Transport and Transformation (ICARTT) study."
