WebApr 13, 2024 · Laser is used in optical fiber communication because it can produce a very high intensity, coherent beam of light that can carry a large amount of information over long distances with minimal signal loss or attenuation. WebLaser beams are said to have high "spatial coherence". This means that the beam is highly concentrated even at long distances (low spread). Can this be achieved with radio waves (much longer waves) or is it due to laser's stimulated emission? electromagnetic-radiation laser Share Cite Improve this question Follow edited Dec 4, 2014 at 12:13

WebArgon laser is a common laser used for treating DR. The main spectral peaks of the argon laser are 488 nm (blue) and 514 nm (green) i.e. relatively shorter wavelengths. Modern argon lasers remove blue wavelength light, allowing photocoagulation to be achieved at 514 nm which reduces light scatter as well as preventing absorption of the blue 488 ... WebSuch a beam can be generated e.g. from the output of a supercontinuum source. Figure 3: A laser beam with high spatial coherence, but poor temporal coherence. Figure 4 shows a laser beam with reduced spatial coherence, but high temporal coherence. The wavefronts are deformed, and this results in a high beam divergence and poor beam quality.
WebMar 14, 2024 · Every point of a laser beam's light waves can be conceived of as being in phase with one another. The monochromaticity or range of wavelengths in the light beam directly affects how coherent it is. Additional Information Laser: A laser emits a very focused beam of light that can be used in a variety of equipment and technologies.
