## Summary

Cardiff University plans to acquire a Mode Hop free tuneable CW laser as part of their ongoing procurement process, which is currently in the planning stage. This procurement falls under the industry category of lasers, coded as CPV 38636100, and will be utilised within the UK, specifically Cardiff. The university has scheduled a future notice date for 3rd March 2025. The key contact person for this procurement is Anna Rogala, who can be reached via email at rogalaa@cardiff.ac.uk or by telephone at +44 2920879648. Interested parties should take note of these details as the opportunity progresses.

This tender poses a significant opportunity for companies specialising in high-precision lasers and related equipment. Businesses that offer cutting-edge laser technology with expertise in mode-hop free tuning and fine wavelength adjustments will find this tender particularly attractive. The laser required must sustain high precision over a wavelength range of 910-940nm and include additional features like single-mode fibre coupling and remote PC control capabilities. Suppliers with the capability to provide these technical specifications, along with robust customer support and integration services, would be well-suited to compete for this contract, facilitating business growth through a high-value engagement with a prominent educational institution.

### Lot Information

Lot 1

Cardiff University is looking into purchasing a Mode Hop free tuneable CW laser. They will use this laser to resonantly drive a semiconductor single quantum dot in the range 910-940nm. The laser must be able to tune continuously over quantum dot transitions. Some lasers "mode hop" (jump in wavelength) and supplier must ensure this product is mode-hop free over the widest range. The laser must have a time-averaged linewidth of less than 1MHz and coarse wavelength setting of less than 0.1nm, in addition to the mode hope free tuning. It should include an optical isolator to prevent back-reflections and have single mode fibre coupling launch 940HP or similar fibre with more than 10mW over the full range of 910-940nm. These parts can be quoted separately, if appropriate. PC control of coarse wavelength tuning, fine piezo wavelength tuning, and intensity should be available over USB, GPIB, ethernet or similar. The supply should include GUI and LabVIEW VIs for remote PC control, a laser interlock connection and/or interlocked shutter. The power supply should be compatible with a UK single phase socket.
