Over the past decade, our group has made great strides in terms of oscillator performance (see other posts on this topics). While that was all exciting, it has also created a new issue, as it meant that we would need to find new ways of measuring such low levels of noise. Out of this necessity, we created a measurement setup,

Every year, more than two billion quartz crystals are sold on the global market. Most of these are used in consumer devices, such as wrist watches, computers and cell phones. Such oscillators are reliable and cheap, but provide limited performance due to mechanical loss in the quartz crystal itself. There is large variety of other electronic oscillators, though all of
We proudly present the world’s first monolithic mode-locked lasers. These lasers are among the quietest free-running oscillators available to date. They can be fully phase stabilized if desired. Low-noise, high-repetition-rate mode-locked solid-state lasers are attractive for precision measurements and microwave generation, but the best lasers in terms of noise performance still consist of complex, bulky optical setups, which limits their
