The Government has determined that no other source has commercial offerings that can meet this requirement of cooling and trapping barium ions. Toptica is the only known company offering a rack-mountable, fiber-coupled, digitally controlled laser system suitable for trapping and manipulating barium ions that meets the criteria of Frequency stability < 100 MHz/K for all 3 channels; Center wavelength of 413nm, 493nm and design wavelength of 650nm. This laser system meets the requirements of the trapped ion lab’s experiments and size weight and power reduction goals.

Awarded contract FA875120P0032 to TOPTICA PHOTONICS, INC for 87643.50 on 2020-07-13.
