…Available in Periodically Poled KTP, Fan-Poled KTP, Bulk KTP and Bulk CTA. Pulse Compressors Pulse Compressors Versatile accessories to compress the broadband pulses and shorten the pulsewidth at the sample. Used for our Vitara, Mira, Chameleon and Vitesse Ti:Sapphire oscillators. Pulse Picker Pulse…
…enhancing contrast; it currently is being
used to determine the margins of cancerous tumors.
"Adaptive spectral control is used with
broadband femtosecond laser pulses to
selectively excite some chromophores but
not others," Dantus said. "Spectral control
is used to…
…a NoiseBlock™ 90/10 beamsplitter filter to a Raman spectrometer with a wavelength stabilized laser source can increase the recovered Raman signal by almost a factor of 4 relative to a broadband 50/50 beamsplitter. The filter’s narrow spectral profile (HWHM 90 % Temperature Dependence 0.01 nm/°C…
…used sources are visible or IR laser sources in the range 500 nm to 1,000 nm; shorter wavelength are more likely to excite fluorescence that can easily hide the Raman scattered light, unless the fluorescence is carefully filtered out. For this reason, near-IR light is often used. Laser sources for…
…acquired as Fourier transforms in the time domain. This
is accomplished using broadband pulses from femtosecond sources to simultaneously span the
frequency region of interest. Here a single broadband source and a pulse shaper generate a
pulse sequence. Timing between two of the…
…monochromatic source that can yield a clean fluorescence signal with very high signal-tonoise ratio. In contrast, the LED is a broadband source that requires the cost and complexity of extra filters, and presents significant cross-talk challenges when detecting multiple fluorochromes. Light Sources…

…simplified
schematic of Fleming's setup (Figure 3)
shows how four different light pulses are
all derived from the same broadband femtosecond source using a simple diffractive
optical element. (The fourth pulse is used
for heterodyne detection.)
This approach "guarantees…
…are used to turn the broadband lasers into
highly tunable single-wavelength sources.
Uses include fluorescence imaging, fluorescence-lifetime imaging microscopy,
OCT, flow cytometry, super-resolution
microscopy, nanophotonics characterization, and broadband spectroscopy.

…sources would fulfil the task, in practice broadband femtosecond pulses are the
method of choice. In addition, the use of short pulses enables also to study the dynamic of
sample, by varying the delay of one of the pulses. The most common accepted method of
obtaining these broadband…
…up to 5

laser with a long pulse width pump source without compromising the seed's transform limited
pulse width. But in the White Dwarf, the Monaco supplies both the seed (signal) and the pump…
