I would like to have at least a vague idea how coherent is light from an inexpensive 1 mW red semiconductor laser which I have.
I tried to find the manufacturer using Google, but I haven't found it.
I would like to know the coherence length and the degree of spatial coherence.
Is there anyone who may give me some information?
