Is there a laser in which based on Ytterbium

I understand that Ytterbium can emit a photon with a relatively high and very accurate frequency (narrow band of frequency). I also know that Ytterbium is being used to verify frequency in atomic watches (a photon with the right frequency can be absorbed, so if the frequency is shifted than the the light will be reflected). So i wondered if there is a laser that use Ytterbium in the gain medium as an emitter. I didn`t find something like that so my question is: Is such laser exist? if not then why?
