Apparently you can't make a laser from sunlight because it contains all frequencies and you make a laser by a certain frequency light and trap it between two mirrors. I assume the distance between the mirrors is critical here. However there is no point in making a laser in what you propose, furthermore there are many solar power plants that work on that idea of creating steam to turn turbines plus the solar towers turn turbines by convection.
