DISCRETE-MODE LASER DIODES
EP689 Discrete-Mode Series – Sr Spectroscopy
The EP689 Discrete-Mode Series laser diode was developed in conjunction with the European Space agency as a frequency reference for Strontium-based atomic clocks.
Suitable for coupling directly to fibre with optical isolation, this laser offers excellent low linewidth performance and stability.
