TU Dublin Physics to Life Sciences Hub wish to replace existing laser equipment. Tenders are sought for two lasers of narrow linewidth/long coherence length, suitable for precision optical applications such as holographic recording. The scope of this procurement includes: i. the first laser will have a wavelength in the green region (likely 532nm), and ii. the second in UV (likely 325nm). The instruments will be used across a broad range of research applications within the institute, accordingly, the proposed lasers must have an extremely high level of spectral purity and stability suitable for holographic applications.
