ITT - Portable 1.5 micron cavity-stabilised laser

Tender description

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 a single 19-inch rack. The complete system shall be transportable, ideally on wheels or castors. Delivery of output light shall be through single-mode, polarisation-maintaining (PM) 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 laboratories and 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).
