We want the laser's linewidth and beam to be high quality to reduce stray light as much as possible. For power we don't have super strong requirements, just not so high that it can burn anything.
Hello!
I am a student working on a project to build a Raman spectrometer with a 650 nm laser. Previously we have used a Picotronic 650 nm 10 mW laser, but were having issues with it's stray light. (It basically had two dots). I am currently in the process of looking for a new laser and was...
