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 ...

   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 ...

4. Laser-induced fluorescence - Wikipedia

   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.

5. Laser linewidth - Wikipedia

   en.wikipedia.org/wiki/Laser_linewidth

   Laser linewidth from high-power high-gain pulsed laser oscillators, comprising line narrowing optics, is a function of the geometrical and dispersive features of the laser cavity. To a first approximation the laser linewidth, in an optimized cavity, is directly proportional to the beam divergence of the emission multiplied by the inverse of the ...

6. Low-level laser therapy - Wikipedia

   en.wikipedia.org/wiki/Low-level_laser_therapy

   Low-level laser therapy (LLLT), cold laser therapy, photobiomodulation (PBM) or red light therapy is a form of medicine that applies low-level (low-power) lasers or light-emitting diodes (LEDs) to the surface of the body.

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.
