Ultrafast optical lasers play an essential role in exploiting the unique capabilities of recently commissioned X-ray free-electron laser facilities such as the Linac Coherent Light Source (LCLS). Pump–probe experimental techniques reveal ultrafast dynamics in atomic and molecular processes and reveal new insights in chemistry, biology, material science and high-energy-density physics. This manuscript describes the laser systems and experimental methods that enable cutting-edge optical laser/X-ray pump–probe experiments to be performed at LCLS.

Optical laser systems for ultrafast X-ray sciences have been established at the Pohang Accelerator Laboratory X-ray Free-Electron Laser (PAL-XFEL) beamlines. Three Ti:sapphire regenerative amplifier systems are synchronized to the XFEL with femtosecond precision, and the low temporal jitter of the PAL-XFEL results in an experimental time resolution below 150 fs (full width at half-maximum). A fundamental wave and its harmonics are currently provided for all beamlines, and tunable sources from ultraviolet to near-infrared are available for one beamline. The position stability of the optical laser extracted from the intensity-based center of mass at the sample position is less than 3% (r.m.s.) of the spot size.

In this analytical review the author describes the main trends in the modern heterodox political economy as an alternative to mainstream economics. Historical specificity as well as the contradictory and uneven character of economic development are examined in detail. The author also discusses problems of class, gender and ethnic discrimination and their influence on economic growth. It is shown that there are tendencies to convergence of different theoretical perspectives and schools, common themes, topics of research and conceptual apparatus are being formed. The forces of integration and differentiation help establish new ideas and receive interesting scientific results in such fields as development economics, macroeconomics and international economics.
