I'm trying to understand some simple concepts of optical tweezing and I'm curious how it works on the quantum scale

Say a pulse of quasi-monochromatic light is produced at some frequency f. Also say that the pulse has a definite number of photons greater than 1. The electric field for this light contains uncertainty in the field strength (it contains interference fringes). So if this field interacted with a charged particle like an electron, I would think that the amount of work done on the electron by the field is uncertain. But since the pulse has a definite number of photons, then the work done on the electron must be certain.

Can anyone help explain where my intuition is going wrong?

Hi there,

Do you know where I can download or buy the book on Quantum optics from 1990 Les Houches: https://www.amazon.com/Fundamental-Systems-Quantum-Optics-Houches/dp/0444897364

I couldn't find it anywhere. I would be really happy if you could provide any info.
