PIN: CR Tuneable Laser · UK public procurement notice

This is a Prior Information Notice for a procurement of CR Tuneable Laser.

The National Physical Laboratory (NPL) seeks the laser source system that must be tuneable over a spectral range from a minimum of 300 nm up to 2500 nm. Its output laser beam should be continuous wave (CW) or high-frequency quasi-continuous wave (e.g., ~80 MHz). The optical power of the emitted beam must be no less than 100 mW across the entire wavelength range. The beam profile should be Gaussian (e.g., TEM00) at all wavelengths. Additionally, the spectral linewidth of the laser source must not exceed 5 nm (Full Width at Half Maximum) throughout the full spectral range. The system should support computer-controlled wavelength setting via LabView and custom Python scripts, allowing automated, hands-free operation. Other requirements include stability in beam intensity (ideally 1 part in 104 over 4 hours), pointing stability (<5.0 µrad over 4 hours), and low spectral background measures (e.g., ASE and SMSR <10-4). The laser system must also be CE or UKCA marked and come with a user manual and onsite service/maintenance contract.
