Lasers precisely stabilized to known transitions between energy levels in simple, well‐
isolated quantum systems such as atoms and molecules are essential for a plethora of …

Nonlinear optical effects in integrated microcavities have been studied extensively with the
advantages of strong light-matter interaction, great scalability, and stability due to the small …

We describe a saturated absorption spectrometer that is robust and compact and requires
minimum alignment, which is made possible by using a diffuse probe beam generated by a …
