Lancaster University Physics

Lancaster University Physics is a UK-based academic research group that packages its in-house laser and ultrafast spectroscopy code into PyMODA, a compact Windows application that imports, models and visualises pump–probe, transient-absorption, fluorescence-upconversion and other time-resolved datasets. Written in Python/NumPy and accelerated with C extensions, the program offers global analysis, lifetime distribution fitting, chirp correction, phasor plotting and animated 3-D surface maps, giving chemists, biophysicists and materials scientists a single desktop workspace for deconvolving overlapping kinetics, extracting relaxation times and publishing ready-to-use graphs. Typical workflows start with raw femtosecond or picosecond decay traces, proceed through automatic instrument-response alignment and multi-exponential regression, and finish with batch export to Origin, MATLAB or TIFF. Because the code originates in an active teaching laboratory, the interface couples research-grade algorithms with step-by-step wizards, making it equally suitable for graduate training courses and for experienced spectroscopists who need rapid turnaround during beam-time schedules. The software is available for free on get.nero.com, where downloads are supplied through trusted Windows package sources such as winget, always install the newest build, and can be queued together with other applications for unattended batch setup.
