External Cavity Diode Lasers (ECDLs)

AOSense External Cavity Diode Laser (ECDL)

Real-world atomic sensors require laser sources with specific size, environmental, and optical characteristics, placing unique constraints that commercial laser systems do not meet. AOSense has developed a line of compact external cavity diode lasers (ECDLs) offering narrow linewidth.

The AOSense ECDL is built on a semi-monolithic bench for stable operation in demanding environments. 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.

ECDL linewidth
The plot above shows a heterodyne beatnote between two free running lasers at 780 nm.  Measurement of the -20 dB width indicates an instantaneous linewidth <30 kHz FWHM.
