Femtosoft Technologies QuickFrog High performance real-time pulse analysis software
QuickFrog is a comprehensive real-time pulse analysis tool for Swamp
Optics GRENOUILLE. QuickFrog continuously monitors
a live FROG trace and applies the FROG retrieval algorithms in real time,
while simultaneously displaying the results of the retrieval.
QuickFrog retrieves all spatio-temporal information
available from the GRENOUILLE, including:
intensity and phase vs. time
spectrum and spectral phase vs. wavelength
spatial chirp
pulse-front tilt
Plus, QuickFrog includes an IEEE-1394
(Firewire) frame grabber that connects directly to the camera in GRENOUILLE. Simply connect to the camera, start QuickFrog, select
your GRENOUILLE model from the QuickFrog device list,
and you're ready to start analyzing pulses!
QuickFrog Temporal
and Spatial Operating Modes
Temporal and spatial operating modes let you change
how QuickFrog handles your trace. In the temporal mode, FROG algorithms
are applied to the data, and laser pulse intensity and phase are recovered.
In the spatial mode, the raw camera signal is displayed, either to align
the trace or to examine the spatial profile of the beam.

Space Mode Display Features
Measured FROG trace from the camera
FROG
trace of the retrieved pulse
Intensity and phase vs. time for the retrieved pulse
Intensity and phase vs. wavelength for the retrieved
pulse
Autocorrelation
The raw (before processing) camera signal, as an
option
A full range of metrics, including:
Pulse FWHM in time domain
Pulse FWHM in frequency domain
FWHM of pulse autocorrelation
FWHM time-bandwidth product of the pulse
RMS time-bandwidth product of the pulse
FROG error (indicates retrieval quality)
Spatial Chirp
Pulsefront Tilt
The raw camera signal, for alignment or to examine
the spatial profile of the beam
The "marginals," the
sum of the signal along the horizontal/vertical axes
Options for the main camera display window include:
Blank mode—simply shows the camera signal
Alignment mode—superimposes a crosshair/bull's-eye
to aid in aligning the device
Slice mode—two side-by-side windows show a slice through the
pulse rather than the sums across the entire camera frame
Additional QuickFrog Features
QuickFrog can save the current
state of the retrieval at any time. This includes:
the measured and retrieved FROG
traces in both JPG and PNG image formats
the measured and retrieved FROG
traces as an ASCII data file
the pulse intensity and phase
as a function of time
the pulse intensity and phase
as a function of wavelength
the pulse metrics
Ability to pause and restart
the data acquisition
Ability to pause and restart
the algorithm
Set the FROG trace center wavelength
from the GUI front screen
Change the camera calibrations
Set the data collection parameters
with a simple GUI interface
Run in single shot mode: the
program will capture a single frame and the perform the retrieval
on it
Perform background dark current
subtractions
