  2. Laser level - Wikipedia

    en.wikipedia.org/wiki/Laser_level

    A rotary laser level set up and used to level sand fill in trenches. The graduated staff is leaning on the pile of sand. In surveying and construction, the laser level is a control tool consisting of a rotating laser beam projector that can be affixed to a tripod. The tool is leveled according to the accuracy of the device and projects a fixed ...

    en.wikipedia.org/wiki/Laser-induced_fluorescence

    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.

    Hychika Green Laser Level: Another fairly inexpensive option, this laser level wins points for its “very crisp and easy to see” green lines and serious durability, according to our tester ...

  5. Laser line level - Wikipedia

    en.wikipedia.org/wiki/Laser_line_level

    A laser line level is a tool combining a spirit level and/or plumb bob with a laser to display an accurately horizontal or vertical illuminated line on a surface the laser line level is laid against. Laser line levels are used wherever accurate verticals and horizontals are required, typically in the construction and cabinetry industries. Some ...

  6. 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. Many different procedures have been developed spanning ...

    en.wikipedia.org/wiki/Spectral_phase_interferome...

    The spectral phase of an ultrashort laser pulse is encoded into a spatial fringe pattern rather than a spectral fringe pattern. Other techniques are frequency-resolved optical gating , streak camera with picosecond response times, and multiphoton intrapulse interference phase scan (MIIPS), a method to characterize and manipulate the ultrashort ...
