We are using Shimadzu SPM-9700HT AFM in the lab. It uses a 650nm laser for cantilever detection. I want to replace the laser to a longer wavelength to avoid excitation of fluorescent samples. If you have experience of replacing the laser unit, would you please be able to share the experience here?

If I were you I would like to disassembly the head where the laser exist and try to put another laser meets the same voltage and current conditions. First is important to check if your laser-detector works with other wavelengths.

Normally laser in AFM system is focused on cantilever (only) and does no affect sample surface.
