Making Molecular Movies at PULSE

High Harmonics

A false colour plot of a High Harmonic Generation spectrum generated by pulsing N2 with an ultrafast laser once, then again after a time delay.

Ultrafast X-rays Probe Electron-Phonon Interactions

Quantum Whirlpools

A dense patterned 3-D grid of tiny whirlpools, called quantum vortices, populates a nanoscale droplet of rotating superfluid helium.

Strong Field-Matter Interaction

Intense ultra-short laser pulses of various colors interact with simple diatomic molecules to emulate and control dynamics of more complex molecular systems.

Photoprotection in DNA

Thymine resists chemical alteration through an ultrafast decay mechanism which we probe using ultrafast pulses in the XUV and SXR domains.

PULSE scientists invent a way to see attosecond electron motions with an X-ray laser

Researchers at the Department of Energy’s SLAC National Accelerator Laboratory have invented a way to observe the movements of electrons with powerful X-ray laser bursts just 280 attoseconds, or billionths of a billionth of a second, long. The technology, called X-ray laser-enhanced attosecond pulse generation (XLEAP), is a big advance that scientists have been working toward for years, and it paves the way for breakthrough studies of how electrons speeding around molecules initiate crucial processes in biology, chemistry, materials science and more.

A quick liquid flip helps explain how morphing materials store information

Experiments at SLAC’s X-ray laser reveal in atomic detail how two distinct liquid phases in these materials enable fast switching between glassy and crystalline states that represent 0s and 1s in memory devices.

PULSE PI Todd Martinez elected to the National Academy of Sciences

The National Academy of Sciences announced today the election of 100 new members and 25 foreign associates in recognition of their distinguished and continuing achievements in original research. Forty percent of the newly elected members are women—the most ever elected in any one year to date.

Those elected today bring the total number of active members to 2,347 and the total number of foreign associates to 487. Foreign associates are nonvoting members of the Academy, with citizenship outside the United States.
