    FIGURE 1. Using multiple laser wavelengths, the BD FACSymphony system is a novel cell analyzer that enables simultaneous measurement of up to 50 different characteristics of a single cell.
    This year is Coherent's 50th anniversary and, in many ways, the company's history and success mirror such trends in the laser industry.

    In the CAOS-CMOS camera setup (left), an incident high-brightness, high-contrast scene is analyzed by two different arms of the camera that operate with different imaging modes. Image reconstruction of the viewed target scene (right) shows a scaled irradiance map (a) of the CAOS-mode-acquired image in a linear scale as well as in a logarithmic scale (b), and finally the CAOS-mode image in (b) is shown with regions of interest that were subject to electronic radio-frequency (RF) signal analysis (c).
    A CAOS-CMOS camera has a three-orders-of-magnitude improvement in dynamic range when compared to conventional CMOS.

    A schematic (a) shows the coupling of WS2 photoluminescence (PL) in surface plasmon polaritons (SPPs). A spectral plot (b) shows WS2 PL and resonant re-absorption of SPPs by underlying WS2; the inset shows an optical image.
    A single material platform is desirable for monolithic integration of photonic and electronic circuits.

    Ultrathin photovoltaic cells made of gallium arsenide (GaAs) with a vertical structure are flexible enough to bend around small objects, such as the 1-mm-thick edge of the glass slide shown here.
    Scientists have made ultrathin 1-μm-thick gallium arsenide (GaAs) photovoltaic cells flexible enough to wrap around a pencil.

    The Brewster-cut Ti:sapphire crystal shows the tight focus from the blue pump diodes.
    High-harmonic sources have very high temporal and spatial coherence, so they can achieve very high temporal and spatial resolution.
