Hello everyone,
I'm working with a poject in relation to acousto-optic deflector. Can anyone tell me what simulation software can simulate the interaction between a pulse laser and acousto-optic deflector? Many thanks
Hello, I mixed two bead sizes, one very low (20nm) and the other 300nm and diluted them with PBS. I varied amount of 300nm and kept the 20nm constant, but I only saw one peak. I should see at...
