It’s like any other fundamental research: you don’t know how much it’s worth until people start using it to solve real problems. This is something that is literally impossible to guess ahead of time. The most abstract mathematical techniques could turn into a trillion–dollar industry (number theory begat RSA encryption which now underpins _everything_ we do). But I will say that precise control of laser wavelength is critical to today’s communication technologies. I doubt their new techniques will be useless.
