Award Notice: Supply of Cavity Stabilised Laser

Award Notice for Supply of Cavity Stabilised Laser: The National Physical Laboratory requirement is for a new compact ultrastable laser system for optical frequency metrology. The ultrastable laser system shall comprise a laser source at 1542 nm frequency-locked to an ultrastable optical cavity, including all necessary optics and electronics for control and monitoring, in one or several 19-inch rack-mount enclosures. Delivery of output light shall be through single-mode fibre. The laser frequency should be user-selectable within a specific range detailed below. The system shall have the ability to be controlled and monitored remotely. It should be designed for reliable continuous operation over extended periods and under environmental conditions typical of data centres. The supply is to include delivery of the performance-verified system ready for installation by the user, any software required to operate the system, a detailed operation manual and a comprehensive performance characterisation (including phase noise and instability).
