    Isolated attosecond pulses (IAPs) in the extreme-ultraviolet range are generated by the interaction of half-cycle mid-infrared pulses with gas (Xe, Kr or Ar) and solid media (quartz). The energy of the IAPs is optically tunable over an octave.

    Variable micropotentials for light are created by thermo-optic imprinting of a dye–polymer solution within a microcavity. A thermalized photon Bose–Einstein condensate as well as the coupling and eigenstate hybridization of sites are demonstrated.

    A unidirectional photonic wire laser has been developed by integrating reflectors into terahertz quantum cascade lasers. The transverse dimension is much smaller than the lasing wavelength (80 μm). A record wall-plug power efficiency of 1% is achieved.

    Single-photon emission with 99% purity is generated from sp3 defects in carbon nanotubes (CNTs) by optical excitation at room temperature. By increasing the CNT diameter from 0.76 nm to 0.94 nm, the emission wavelength can be changed from 1,100 nm to 1,600 nm.

    More than 500 near-infrared laser photons are scattered by a single electron into a single X-ray photon. This is the first experimental evidence of high-order multiphoton Thomson scattering and validates the decades-old theoretical predictions.
