High-power, frequency-quadrupled UV laser source resonant with the S-P narrow intercombination transition of cadmium at 326.2 nm.

We present a novel high-power, frequency-stabilized UV laser source at 326.2 nm, resonant with the Cd S-P narrow intercombination transition. We achieve a maximum produced power of 1 W at 326.

Watt-level blue light for precision spectroscopy, laser cooling and trapping of strontium and cadmium atoms.

High-power and narrow-linewidth laser light is a vital tool for atomic physics, being used for example in laser cooling and trapping and precision spectroscopy. Here we produce Watt-level laser radiation at 457.75 nm and 460.
