This is by far the most important type of laser commercially, as it can be made relatively cheaply, and it doesn't break easily as it ends up being a single crystal.

Compare them for example to the earlier gas lasers.

This is the type of laser that you would get in a simple laser pointer.

But the real mega aplications are:

Closely related to optical amplifiers.

This section is about stuff efficiently getting light into or out of optical fibers, or joining two optical fibers together end to end so that light goes through.

Historically this has been an important development, as it is much harder than with wires since optical fiber has to be very narrow to work properly, e.g. this is mentioned a lot in City of Light: The Story of Fiber Optics.
