Ultrashort

Atoms in a crystal form a regular lattice, in which they can move over small distances from their equilibrium positions. Such phonon excitations are represented by quantum states. A superposition of phonon states defines a so-called phonon…

An international team of laser physicists of the attoworld team at LMU and the Max Planck Institute of Quantum Optics has achieved unprecedented control over light pulses in the mid-infrared wavelength range. Ultrashort infrared light…

LG just took the wraps off a new flagship CineBeam ultra-short throw (UST) projector, model HU915QE. The 4K three-channel laser projector blasts a super bright 3,700 ANSI lumen image that measures 100 inches when placed just 9.8cm (3.9…

Stable packets of light waves -- called optical solitons -- are emitted in ultrashort-pulse lasers as a chain of light flashes. These solitons often combine into pairs with very short temporal separation. Introducing atomic vibrations in…

Televisions are ugly. A 55-inch television creates about 1,300 square-inches of eyesore when not in use. Many don’t care, but my spouse does, which meant living with a tiny TV for longer than I care to admit. Ultra-short throw…

Ultrashort pulses of light are proven indistinguishable from continuous illumination, in terms of controlling the electronic states of atomically-thin material tungsten disulfide (WS2). A new, Swinburne-led study proves that ultrashort…
