  2. Laser-induced breakdown spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Laser-induced_breakdown...

    Laser-induced breakdown spectroscopy (LIBS) is a type of atomic emission spectroscopy which uses a highly energetic laser pulse as the excitation source. [1] [2] The laser is focused to form a plasma, which atomizes and excites samples. The formation of the plasma only begins when the focused laser achieves a certain threshold for optical ...

  3. Wolfgang Demtröder - Wikipedia

    en.wikipedia.org/wiki/Wolfgang_Demtröder

    He is the author of several textbooks on laser spectroscopy and a series of four textbooks on experimental physics. His books entitled Laserspektroskopie [1] and Laser Spectroscopy [2] [3] are considered classics in the field. From 1970 til 1999, he was ordinary professor at Kaiserslautern University of Technology. [4]

  4. Laser-based angle-resolved photoemission spectroscopy

    en.wikipedia.org/wiki/Laser-based_angle-resolved...

    Femtosecond laser-based ARPES can be extended to give spectroscopic access to excited states in time-resolved photoemission and two-photon photoelectron spectroscopy. By pumping an electron to a higher level excited state with the first photon, the subsequent evolution and interactions of electronic states as a function of time can be studied ...

  5. Laser absorption spectrometry - Wikipedia

    en.wikipedia.org/wiki/Laser_absorption_spectrometry

    Laser absorption spectrometry (LAS) refers to techniques that use lasers to assess the concentration or amount of a species in gas phase by absorption spectrometry (AS). Optical spectroscopic techniques in general, and laser-based techniques in particular, have a great potential for detection and monitoring of constituents in gas phase.

  6. Laser-induced fluorescence - Wikipedia

    en.wikipedia.org/wiki/Laser-induced_fluorescence

    Laser-induced fluorescence (LIF) or laser-stimulated fluorescence (LSF) [1] is a spectroscopic method in which an atom or molecule is excited to a higher energy level by the absorption of laser light followed by spontaneous emission of light. [2] [3] It was first reported by Zare and coworkers in 1968. [4] [5]

  7. Ultrafast laser spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Ultrafast_laser_spectroscopy

    Ultrafast laser spectroscopy is a category of spectroscopic techniques using ultrashort pulse lasers for the study of dynamics on extremely short time scales (attoseconds to nanoseconds). Different methods are used to examine the dynamics of charge carriers, atoms, and molecules.

  8. Laser diffraction analysis - Wikipedia

    en.wikipedia.org/wiki/Laser_diffraction_analysis

    Laser diffraction analyzer. Laser diffraction analysis, also known as laser diffraction spectroscopy, is a technology that utilizes diffraction patterns of a laser beam passed through any object ranging from nanometers to millimeters in size [1] to quickly measure geometrical dimensions of a particle.
