TITLE: Calcium PI laser system Requesting Lab/Division/Group: Physical Measurements Lab/Time and Frequency Division/ Ion Storage Group

NB688000-25-01506

General Statement of Need The Physical Measurements Lab/Time and Frequency Division/Ion Storage Group at NIST performs a variety of quantum computing, quantum simulation, and optical clock experiments using trapped ions. These experiments rely on the use of frequency-stabilized lasers of a variety of wavelengths to drive specific atomic transitions. We require multiple lasers to photoionize neutral calcium 40 atoms, as well as electronics to drive the lasers. For calcium 40, this is a two stage process. One laser at 422 nm needs to excite the neutral calcium atom, and then a second laser at 375 nm excites the electron into the continuum to ionize the atom. Each laser needs an output power of 10s of mW, and the 422 nm laser needs a linewidth < 1 MHz and needs to have the ability to be locked to a wavemeter with a few kHz bandwidth. Driving current and temperature electronics are also required. See specifications below for more details.
