ITT - Portable 1.5 micron 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 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 las...
