The layer of gases that we breathe also distorts the images formed by telescopes. This means that conventional telescopes of more than a few centimeters in diameter cannot reach the resolution limit set by their optics.To Isaac Newton the problem was clear, and in 1704 he realized the effects of atmospheric turbulence on image formation. Just as heat waves shimmering above a hot patch of ground can distort our...Photonics HandbookTunable Lasers: Generating Wavelengths from the UV Through the IR: Many lasers allow the operator to tune or change the output wavelength from the UV to the IR on demand.Applications facilitated by tunable lasers can be divided into two basic categories.
