CAN: Procurement of Tuneable Lasers

The National Physical Laboratory (NPL) requirement is for the supply of two tuneable lasers required for beating with devices under test as part of linewidth measurements. As NPL is developing the understanding of linewidth measurement techniques in the context of various applications involving many different laser types, lasers with a narrow linewidth and tuneability over a range of wavelengths are required to perform heterodyne measurements of the devices under test. The primary requirement is for two lasers, one...
