…light at one frequency,
coherent pulses of broadband light are
used so that all frequencies are recorded
simultaneously. Data is measured as a
function of the time between the pulses
and FT converted into the frequency domain, giving the excitation frequency
axis. The…

…effect occurs when a sample is irradiated with UV, visible or IR light and a small fraction of the incident radiation is scattered and shifted at frequencies that correspond to vibrational transitions specific of the sample. The Raman signal is much weaker than the incident and scattered light, so…

…Unfortunately, the manual process involved in grinding is not repeatable and it requires high user skills. By using the ExciStar at 248 nm or a frequency tripled DPSS laser emitting 355 nm like the AVIA, it is possible to precisely scarf the damaged area – allowing layers of composite to be ablated…

…generation
In the SFM process described in the previous 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…

if two frequency combs of slightly different pulse repetition frequencies are
used. A single fast photodetector reveals
radio frequency beat notes between corresponding lines from each comb, and
there is no need for any moving parts.
To achieve similar recording…

crystal. And for applications needing ultraviolet output, some OPSLs are also equipped with a
pair of intracavity crystals to perform frequency tripling.
