Scientific
In science, lasers are used in many ways, including:
- A wide variety of interferometric techniques
- Raman spectroscopy
- Laser induced breakdown spectroscopy
- Atmospheric remote sensing
- Investigating nonlinear optics phenomena
- Holographic techniques employing lasers also contribute to a number of measurement techniques.
- Laser based LIght Detection And Ranging (LIDAR) technology has application in geology, seismology, remote sensing and atmospheric physics.
- Lasers have been used aboard spacecraft such as in the Cassini-Huygens mission.
- In astronomy, lasers have been used to create artificial laser guide stars, used as reference objects for adaptive optics telescopes.
Lasers may also be indirectly used in spectroscopy as a micro-sampling system, a technique termed Laser ablation (LA), which is typically applied to ICP-MS apparatus resulting in the powerful LA-ICP-MS.
The principles of laser spectroscopy are discussed by Demtröder and the use of tunable lasers in spectroscopy are described in Tunable Laser Applications. ).

Famous quotes containing the word scientific:
“Now, I hold it is not decent for a scientific gent
To say another is an ass—at least, to all intent;
Nor should the individual who happens to be meant
Reply by heaving rocks at him to any great extent.”
—Bret Harte (1836–1902)
“In the domain of Political Economy, free scientific inquiry meets not merely the same enemies as in all other domains. The peculiar nature of the material it deals with, summons as foes into the field of battle the most violent, mean and malignant passions of the human breast, the Furies of private interest.”
—Karl Marx (1818–1883)
“To develop an empiricist account of science is to depict it as involving a search for truth only about the empirical world, about what is actual and observable.... It must involve throughout a resolute rejection of the demand for an explanation of the regularities in the observable course of nature, by means of truths concerning a reality beyond what is actual and observable, as a demand which plays no role in the scientific enterprise.”
—Bas Van Fraassen (b. 1941)
