however if you know about thermodynamics and about the laws concerning entropy you would know that there needs to be a certain amount of heat in teh surrounding for more heat to eb generated and carried logn distances. While you are correct stating the sun carries heat, you forgot that the suns heat produces incoherent photons, while lasers are coherent.
