BELLA Laser Achieves One Pulse Per Second For World Record Power
For the first time, Lawrence Livermore researchers and international collaborators have peered into the makeup of complex airborne particulate matter so small that it can be transported into human lungs -- usually without a trace.
"For the first time we can actually see the structure of individual aerosol particles floating in air, their 'native habitat'," said DESY scientist Henry Chapman from the Center for Free-Electron Laser Science (CFEL) in Hamburg.
The structure of biomolecules is of great interest for medicine and biology because their shape often determines their function. The use of new tools called free-electron lasers (FELs) allows scientists to obtain high-resolution structural insight into macromolecules.
For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds (a femtosecond is one quadrillionth of a second).
A team of physicists at UC Santa Barbara has seen the light, and it comes in many different colors.
Lab scientists and international collaborators have created the shortest, purest X-ray laser pulses ever achieved, fulfilling a 45-year-old prediction and ultimately opening the door to new medicines, devices and materials.
In two separate studies, the world’s most powerful X-ray laser has been used to build the first atomic X-ray laser pulse, as well as to superheat and control a clump of 2-million-degree matter.
Together with international colleagues, scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have added another important component towards understanding the material graphene; a material that is currently receiving a lot of attention: They have determined the lifetime of electrons in graphene in lower energy ranges.
A new class of high power lasers can effectively accelerate particles like electrons and ions with very intense, short laser pulses.
