Could we use lasers instead of radio, like the Starlink laser inter-links or the NASA ILLUMA-T/LCRD demonstration?

    Maybe in the future, but the existing Mars orbiters need to hear a strong radio signal. And laser communication has not yet been tested outside of Earth orbit. It will need to be significantly scaled up to handle the 2-3AU distance.
