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 , 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.
