Yes, it’s called radiation pressure by emmision

The formula for it is Irradiance^1 of the emission/speed of light.

1: irradiance is basically how much power per unit area is emmited by the object, it’s units are watt/m^2

As for the lasers thing, I’m not a 100% sure how effective that will be and TBH lasers are pretty complicated and I don’t really get them
