Fabry-Pérot etalon walk-off loss in ring cavities Open
Fabry-Pérot etalons are widely used for laser frequency control. Inserting them in laser cavities imparts unavoidable walk-off loss and reduces the output power. Here, we treat the technology-relevant case of the walk-off loss of an etalon…

High-resolution, broadly-tunable mid-IR spectroscopy using a continuous wave optical parametric oscillator Open
We report on the design and automation of a mid-infrared, continuous wave, singly-resonant optical parametric oscillator. Hands-free controls and the implementation of a tuning algorithm allowed for hundreds of nanometers of continuous, ef…

11-watt single-frequency 1342-nm laser based on multi-segmented Nd:YVO<i/> <sub>4</sub> crystal Open
High power continuous-wave (CW) single-frequency 1342 nm lasers are of interest for fundamental research, particularly, for laser cooling of lithium atoms. Using the popular Nd:YVO4 laser crystal requires careful heat management, because s…

A noise-immune cavity-assisted non-destructive detection for an optical lattice clock in the quantum regime Open
We present and implement a non-destructive detection scheme for the\ntransition probability readout of an optical lattice clock. The scheme relies\non a differential heterodyne measurement of the dispersive properties of\nlattice-trapped a…

24-watts second-harmonic generation in ppZnO:LN ridge waveguide for lithium laser cooling Open
We present a simple all-solid-state laser source emitting 2.4 W of single-frequency light at 671 nm for laser cooling of lithium atoms. It is based on a diode-pumped solid-state laser, which is frequency doubled in a ppZnO:LN ridge wavegui…
