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:
“Truth is that concordance of an abstract statement with the ideal limit towards which endless investigation would tend to bring scientific belief, which concordance the abstract statement may possess by virtue of the confession of its inaccuracy and one-sidedness, and this confession is an essential ingredient of truth.”
—Charles Sanders Peirce (1839–1914)
“I philosophize from the vantage point only of our own
provincial conceptual scheme and scientific epoch, true; but I know no better.”
—Willard Van Orman Quine (b. 1908)
“The conclusion suggested by these arguments might be called the paradox of theorizing. It asserts that if the terms and the general principles of a scientific theory serve their purpose, i. e., if they establish the definite connections among observable phenomena, then they can be dispensed with since any chain of laws and interpretive statements establishing such a connection should then be replaceable by a law which directly links observational antecedents to observational consequents.”
—C.G. (Carl Gustav)
