Laser power and wavelength trade off SNR and fluorescence background

Claim that a higher-powered laser or a different wavelength (e.g., 785 nm) may increase signal and reduce fluorescence background in biological samples, but may impact Raman scattering intensity.

Evidence Quote

A higher-powered laser would allow for potentially more signal ... A different wavelength ... could decrease the background fluorescence ... but may have trade-offs in the intensity of the Raman scattering
