The light emitted by a laser has an associated energy (Energy = Plank's Constant(times)frequency of the light => E=h*f). If the energy is high enough coupled with amplification techniques this energy can be utilized the induce fusion of the fuel. The fuel can be Deuterium-Deuterium, Deuterium-Tritium, Deuterium-Helium(3), or Hydrogen-Boron. The fusion of these atoms leads to product atoms and the release of energy.
Stars are driven by Nuclear Fusion.
Yes, inertial confinement fusion uses high-energy lasers to compress and heat a fuel pellet, typically containing deuterium and tritium, to trigger a nuclear fusion reaction. The intense laser beams are focused on the fuel pellet to create the extreme conditions necessary for fusion to occur.
Nuclear fusion is feasible, and both magnetic confinement fusion (MCF) and inertial confinement fusion (ICF) are promising approaches to achieve it. MCF uses strong magnetic fields to confine and heat the plasma, while ICF involves using intense laser or particle beams to compress and heat the fuel. Both methods have made significant progress in recent years towards achieving sustained fusion reactions.

No, a fission reaction is not necessary to trigger a fusion reaction, but for us on earth, it is. In the field of nuclear weapons, a fission bomb is needed to create the heat necessary to set off a fusion weapon. We have to use fission, or, rather, the energy created by that, to initiate the fusion reaction. It might be possible to use a high power source, like a laser, on a small amount of material to get fusion to occur. But we are still experimenting with this in the Tokamak, and it's far from being a done deal. Stars are, in general, massive nuclear fusion reactors. Their constant consumption of fuel powering their high rate of fusion creates a massive amount of energy, and the stars' huge gravity keeps this process from blowing the whole thing apart. No fission is needed to sustain this reaction.

TO initiate fusion process very high temperature of the order of 100 million kelvin is needed. Such a high temperature could be produced by laser beam if it is used in a different technique. That is why sciectists rely on laser.
There aren't any 'plants' as such, only experimental rigs. This is an attempt to see if lasers could be used to produce fusion. The idea is to focus a very powerful laser beam onto a small capsule of nuclear fuel and see if the intense heat produced will produce fusion. See link below
There are fuel pellets and laser beams inside fusion reactors. But note that we have not build a successful one. The technical problems are overwhelming at this point.
