There was a time when the only solid-state lasers had to be operated at liquid nitrogen temperatures (-196°C), and emitted only infrared light.
Today they operate at room temperature and above, emit visible light at high intensity, and cost just a few dollars. They are in every CD and DVD player, as well as laser pointers and 3-D printers, and elsewhere.
