Can We Bend Space Just From Photons or Gravitational Waves?

Can we detect the bending of space from just photons and or all that energy flying around the universe? Yes, i think there's two different answers here. One is like, is it possible? Could you do this? And the other is like, wide we see it more happening in the universe to day? To answer the first one, we think that if you took enough lazers that were powerful enough and you focused them on a single point so that you overlapped a huge number of photons in a tiny little space then you would create a black hole.
