Answer Question: How to combine two laser beams into one optical fiber?

I've built a small diy laser cutter using a 2000mw laser diode. I'd like to know how I could combine two laser beams into a fiber optic cable and focus into single point. The idea is I'd like to increase cutting power by using two laser diodes instead of just one. Furthermore, I'd like to use a fiber cable so the laser diodes do not need to be mounted on the X-gantry and I can route the laser beam as I see fit. Is it possible to combine two 445nm 2000mw (continuous power) laser beams into a fiber cable and focus laser beam into a single point? If so, how is this accomplished? I would need you to provide a thorough description and details on how to accomplish this.
