Introducing the STABIλASER 1542ε
The Stabiλaser 1542ε is a 2nd generation acetylene-stabilized laser that exhibits both narrow line width, excellent long-term stability and high accuracy. The design maintains the short-term line width of a high-end fiber laser, and adds the long-term stability and accuracy from a molecular transition of acetylene. The result is a high-performance laser source offering continuous trouble-free operation without user intervention.
ABOUT THE STABIλASER EPSILON EDITION
Updated design
Smaller, lighter and rack mountable 3U chassis
Control PC integrated into the chassis
New 771 nm module option, this option can be retrofitted subsequently
100 mW EDFA input/output removed from the front panel
Lock TTL moved to the back
Improved internal design so the laser is less sensitive to external temperature fluctuations
Applications
Thanks to the stable, accurate and narrow-linewidth optical output the Stabiλaser 1542ε can be used in a wide variety of applications, including stabilization of optical frequency combs and length metrology. As a reference, the Stabiλaser 1542ε is an essential component for stabilization and line narrowing of lasers for spectroscopy or laser cooling on narrow-line atomic or molecular transitions, as well as in dual comb spectroscopy, quantum information and telecom applications.
Technology
At the heart of the Stabiλaser 1542ε is a compact ultra low-noise fiber laser stabilized to the acetylene 13C2H2P(16) (v1+ v3) transition at λ= 1542.3837 nm, corresponding to the frequency f = c/λ= 194 369 569 384 kHz. The laser meets the conditions of the CIPM recommendation on standard frequencies and can be used as a primary standard with an uncertainty of 5 kHz. The proprietary optical design and control software ensure both autonomous operation and high quality laser output.
Easy to use
The Stabiλaser 1542ε comes in a 19-inch rack-mountable chassis and is controlled by an internal PC, making it easy to integrate into existing systems. Great emphasis has been placed on robustness and signal integrity, resulting in a high-performance laser that operates smoothly without user intervention. The graphical user interface is simple and user-friendly, displaying exactly what is needed to operate the Stabiλaser 1542ε and monitor the essential parameters.

Abstract
Enhancement of the performance of a fiber-based frequency comb by referencing to an acetylene-stabilized fiber laser
In the paper, authored by Thomas Talvad, Phillip G. Westergaard, Michael V. DePalatis, Nicolai F. Mortensen, Michael Drewsen, Bjarke Gøth, and Jan Hald, published in Optics Express (Vol. 25, pp. 2259-2269, 2017), the research was supported by the following organizations:
- Danish Agency for Science, Technology and Innovation
- EU FP7 (Q-Tea)
- Innovation Fund Denmark (Qubiz)
- The Danish Council for Independent Research (Sapere Aude DFF-Advanced Grant)
The graphical user interface emphasizes simplicity and user-friendliness. Only the essentials are displayed to operate the Stabiλaser 1542ε and to monitor a few key parameters.
