…molecules. Moreover, the high peak power of these lasers enables the generation of many nonlinear processes; that is, processes where two, three or more photons simultaneously interact with a target. Thanks to the short pulse duration and high peak power, the advent of femtosecond lasers in the…

…brightness of a laser source. Monochromaticity - A photon's energy determines its wavelength through the relationship E = hc/, where h is Planck's constant, c is the speed of light, and is wavelength. An ideal laser would emit all photons with exactly the same energy, and thus the same wavelength,…

…section, two photons at different frequencies interact to produce a single photon at a frequency that is the sum of the two initial frequencies. The opposite process is also possible: A single photon interacts with a suitable crystal and disappears, creating two photons of lower and different…

…colleagues have achieved sampling rates of ~50,000/s and, thus, rates as high as 1000 fps for 50 sampling sites. They also extended the approach to three dimensions; without moving the objective lens, 3-D RAMP microscopy enables them to spatially sample sites in a volume at the same sampling rate,…
