Oh, no, not again :)

But wait... if it happens again and again, _I_ don't have to
do it again!

"if anything can start anew, then everything must continue"

So yes, here is an example:

Note: The keywords don't have to be expressions BTW. They can
be single words. Then, instead of the index (1 in the example)
just add a dot, i.e. (word . face)

\alpha^{high}
\beta_{low}

(progn
  (font-lock-add-keywords
   'emacs-lisp-mode
   '(
     ("\\^{\\([[:alnum:]]*\\)}" 1 font-lock-builtin-face)
     ("_{\\([[:alnum:]]*\\)}"   1 font-lock-function-name-face)
     )
   t)
  (text-mode)
  (emacs-lisp-mode) )
;;                   ^ eval

You can see the result in this screenshot:
