“…By use of a long pass filter (Thorlabs FEL550, transmission at 532 nm, 1.3 × 10 −6 ), the pulse energy of Rayleigh scattering can be further reduced down to 10 −4 to 10 −3 aJ, which is well below the detection limit of FNOPAS. 15 As a result, combination of the Cassegrain objective and one long pass filter with proper cut-off wavelength can guarantee FNOPAS free of the interference from the coherent photons.…”

We report an improved setup of femtosecond time-resolved fluorescence non-collinear optical parametric amplification spectroscopy (FNOPAS) with a 210 fs temporal response. The system employs a Cassegrain objective to collect and focus fluorescence photons, which eliminates the interference from the coherent photons in the fluorescence amplification by temporal separation of the coherent photons and the fluorescence photons. The gain factor of the Cassegrain objective-assisted FNOPAS is characterized as 1.24 × 10(5) for Rhodamine 6G. Spectral corrections have been performed on the transient fluorescence spectra of Rhodamine 6G and Rhodamine 640 in ethanol by using an intrinsic calibration curve derived from the spectrum of superfluorescence, which is generated from the amplification of the vacuum quantum noise. The validity of spectral correction is illustrated by comparisons of spectral shape and peak wavelength between the corrected transient fluorescence spectra of these two dyes acquired by FNOPAS and their corresponding standard reference spectra collected by the commercial streak camera. The transient fluorescence spectra of the Rhodamine 6G were acquired in an optimized phase match condition, which gives a deviation in the peak wavelength between the retrieved spectrum and the reference spectrum of 1.0 nm, while those of Rhodamine 640 were collected in a non-optimized phase match condition, leading to a deviation in a range of 1.0-3.0 nm. Our results indicate that the improved FNOPAS can be a reliable tool in the measurement of transient fluorescence spectrum for its high temporal resolution and faithfully corrected spectrum.

“…We have recently made significant progress in all of these areas. It is now possible to measure ultrashort light www.lpr-journal.org pulses whose time-bandwidth product exceeds 1000 [21], pulses with as little as a few hundred photons (and simultaneously with poor spatial coherence and random absolute phase) [22], and pulses with spatio-temporal distortions like spatial chirp and pulse-front tilt [23,24]. It is also possible to measure very complex pulses in a train in which each is different.…”

We describe experimentally simple, accurate, and reliable methods for measuring from very simple to potentially very complex ultrashort laser pulses. With only a few easily aligned components, these methods allow the measurement of a wide range of pulses, including those with time-bandwidth products greater than 1000 and those with energies of only a few hundred photons. In addition, two new, very simple methods allow the measurement of the complete spatio-temporal intensity and phase of even complex pulses on a single shot or at a tight focus.Side views of an ultrashort laser pulse focusing in the presence of spherical aberration and group-velocity dispersion (GVD) and measured by Pamela Bowlan using SEA TADPOLE. In the nine snapshots, the color indicates the actual pulse color vs. space and time before and after the focus. The white dots represent the pulse-front (the highest intensity for a given transverse coordinate). The fringes in the beam before the focus are due to spherical aberration, and the rainbow-like appearance is due to the GVD. A short pre-history of ultrashort-laser-pulse measurementIn the 1960s, researchers began generating laser pulses shorter than could be measured using electronic detectors, and the field of ultrashort-laser-pulse measurement was born. How to measure humankind's shortest events? The goal was (and still is) to measure the pulse electric field vs. time, that is, its intensity, I(t), and phase, φ(t):or, equivalently, in the frequency domain, the pulse spectrum, S(ω), and spectral phase, ϕ(ω):Ẽomitting the negative-frequency component of the pulse. In principle, a shorter event is necessary to make the measurement. But clearly no such event was available. Researchers quickly realized that the shortest event available was the event itself. Thus autocorrelation [1] was born. Autocorrelation involved splitting the pulse into two, spatially overlapping the two pulses in some instantaneously responding nonlinear-optical medium, such as a secondharmonic-generation (SHG) crystal (See Fig. 1), and variably delaying one pulse with respect to the other. A SHG crystal produces light at twice the frequency of the input
