SupernovaSN 2006gy is hypothesized to have been a pair production type supernova.

Another example is pair production in very strong electric fields, sometimes called vacuum decay.

Higher intensity means that photons are crowded more densely together, making events such as pair production more likely.

In semiclassical general relativity, pair production is also invoked to explain the Hawking radiation effect.

Above 5 MeV, pair production starts to dominate.

Feynman diagram for pair production.
From the en.wikipedia.org
Pair production and nuclear fusion are processes through which measurable amounts of mass and energy are converted into each other.
From the en.wikipedia.org
The reverse process, pair production, is the dominant mechanism by which high-energy photons such as gamma rays lose energy while passing through matter.
From the en.wikipedia.org
This equivalence is exemplified in a large number of physical processes including pair production, nuclear fusion, and the gravitational bending of light.
