It is a very strong possibility, in fact at first I thought that the laser I really had was the CPS532-C2, since that would fit better with what I was observing. However, I have now fully confirmed that the laser I have is the CPS532 with a much higher power. To verify this, I have contacted...

In the next few days I will try using another laser to see if the same thing happens, with that I will be able to discard whether this behavior comes from the setup or if it arises from the laser, as soon as I have the answer I will return with my observations!

I understand, that would generate a change in the visibility of the pattern. But, using a grating I checked to see if I could observe another mode in the laser, but even at a great distance I could only identify a single mode. So the fact that I can see this behavior when there is only one mode...

I see what you mean, I was just looking for some kind of reference to work from, but I know it's quite possible that the coherence length was different. But I didn't expect it to be that long, that's the real question, because I was able to measure the interference pattern along almost 60 cm of...

Sorry, this is the real link: https://lenlasers.ru/upload/iblock/485/EDU_MINT2_M_Manual.LLS.pdf , page 29

Let me explain the situation: I have an experimental setup consisting mainly of a Michelson interferometer, so I want to use it to measure the coherence length for two different situations, when the beam is focused on a mirror and when it is focused on a sample. Therefore, before analyzing the...
