(a) Relative Raman intensity at 1838 cm−1 (attributed only to fluorescence) of a 40 mg·ml-1 BSA solution with different nominal laser powers as a function of time with 532 nm excitation in the ChiralRAMAN-2X™ without recirculation. (b) I/I0 of 900, 700, and 500 mW photobleaching curves in log scale with trendlines overlaid.
