We could use lasers to transfer energy to spaceships but..
That would become less and less practical as the distance grew. The longer the distance the bigger portion of the laser would miss the panels used to absorb the energy. You can of course compensate by making the panels larger but that does add weight.
While this could be used to for example deliver energy needed for life support system the most efficient solution is probably to just use it for propulsion and simply have the laser light be reflected (doubling the impact in terms of propulsion). That could drastically reduce or outright eliminate the need for rocket fuel to speed the rocket up after it has left earth allowing more fuel to the used for life support and to later slow the rocket down.
And if we manage to establish enough equipment on the target planet we could potentially also use laser to slow the spaceship down as well but that is easier said than done.
So instead we we will have to combine the following 3 to slow down the spacecraft
0. Fission-reactor/engine inside the space-craft.
1. The interstellar medium slowing down the spaceship.
2. Light from the star we travel to slowing down the spaceship (will be more effective if we can have the mirrors survive that long).
One big issue with laser propulsion is that it's very inefficient in terms of how powerful laser you need relative to the force you actually get out of it from the light being reflected. It's mainly useful for very light spacecrafts.

And that was not some plan for colonization since they didn't even try to develop technology to be able to slow down. All they tried to do was getting a photo of the planet but even that doesn't seem possible during our lifetimes.
It's not that we cannot do it it's that we probably have to settle for significantly lower speeds which means that we will probably not live to see the fruits of our efforts. Our children may however get to see it.
