Chlamydomonas spectrum changes under continuous laser exposure

Claim that over a 20-minute time series of solid cultures under continuous laser, Chlamydomonas reinhardtii 124 spectra showed changing fluorescence background and decreasing peak intensities, potentially due to fluorescence obscuring Raman signal or pigment changes.

Evidence Quote

Chlamydomonas spectra over time: background increases, peaks diminish.
