Deep Laser Cooling and Efficient Magnetic Compression of Molecules. [PDF]
Physical Review Letters, 2018 We introduce a scheme for deep laser cooling of molecules based on robust dark states at zero velocity. By simulating this scheme, we show it to be a widely applicable method that can reach the recoil limit or below.

The possibility of using laser and micro-jet technology in the welding of structural elements of vehicles [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2015 A paper presents the possibility of laser welding using micro-jet cooling. The effect of micro-jet cooling on microstructure and mechanical properties of the weld metal deposit was carried out.

Λ-enhanced grey molasses on the D2 transition of Rubidium-87 atoms
Scientific Reports, 2018 Laser cooling based on dark states, i.e. states decoupled from light, has proven to be effective to increase the phase-space density of cold trapped atoms.

Chinese Journal of Mechanical Engineering, 2019 In order to control the ferrite and austenite percentage in duplex stainless steel welding, many researchers try to change the laser welding parameters and cooling medium, but ignore to study the influence of heat sink effect on weld strength.

Laser Cooling of Molecular Anions [PDF]
Physical Review Letters, 2015 We propose a scheme for laser cooling of negatively charged molecules. We briefly summarise the requirements for such laser cooling and we identify a number of potential candidates. A detailed computation study with C$\_2^-$, the most studied molecular anion, is carried out.

FEBS Open Bio, EarlyView.Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Three-dimensional model of small signal free-electron lasers
Physical Review Special Topics. Accelerators and Beams, 2011 Coherent electron cooling is an ultrahigh-bandwidth form of stochastic cooling which utilizes the charge perturbation from Debye screening as a seed for a free-electron laser.
