Introducing the Stabiλaser 1542ε
The Stabiλaser 1542ε (epsilon edition) is a 2. gen acetylene-stabilized laser that exhibits both narrow linewidth, excellent long-term stability and high accuracy. The design maintains the short-term linewidth of a high-end fiber laser, and adds the long-term stability and accuracy from a molecular transition of acetylene.
Some of the changes to the new epsilon edition:
- The design has been updated
- The new 3U chassis is smaller, lighter and rack
- The control PC is integrated into the chassis
- New 771 nm module option, this option can be
- The 100 mW EDFA input/output have been removed
from the front panel
- The Lock TTL has been moved to the back
- The internal design has been improved so the laser is
less sensitive to external temperature fluctuations
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.
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.
The Stabiλaser 1542ε is available in a 19 inch rack mountable chassis and is controlled by an internal PC, easily integrated into existing setups. Robustness and signal integrity have been topics of particular attention during the design and test of the Stabiλaser 1542ε. The result is a high-performance laser source offering continuous trouble-free operation without user intervention.
The graphical user interface excels with its simplicity and user-friendliness, showing exactly what you need to put the Stabiλaser 1542ε into operation and to monitor the essential parameters.
