laser sysReal-world atomic sensors require laser sources and laser systems with severe costrains in terms of size, stability, and optical characteristics, placing unique characteristics that commercial laser systems do not meet.

AtomSensors has developed a line of compact laser systems based on miniaturized optical montage and external cavity diode lasers (ECDLs) offering narrow linewidth (<100 kHz) and high output power. The wavelength is factory-set to the desired user wavelength; no subsequent mechanical adjustment is required. The output beam is circularized to optimize fiber coupling. Current wavelengths include alkali (767 nm, 780 nm, 852 nm) and alkaline earth (423 nm, 461 nm, 657 nm, 689 nm, 698 nm) transitions. The flexible design is fully translatable to additional wavelengths.
