n two new studies, researchers at the National Institute of Standards and Technology (NIST) have greatly improved the efficiency and power output of a series of chip-scale devices that generate laser light at different colors while all using the same input laser source.
Many quantum technologies, including miniature optical atomic clocks and future quantum computers, will require simultaneous access to multiple, widely varying laser colors within a small region of space. For instance, up to six different laser colors are needed for all the steps required for a leading atom-based design for quantum computation, including preparing the atoms, cooling them, reading out their energy states, and performing quantum logic operations.
