I've got a 28 THz laser! I've even got a 744 THz laser in pointer form. (co2 and violet diode respectively) :shhh:

Wikipedia tells me those don't count though, because apparently only 0.3 to 3 terahertz counts as terahertz radiation. :can:

Funny reading all the seemingly arbitrary labels for regions of the spectrum on the same plot.
