Procurement of a tunable laser 1420nm to 1530nm

At the department Quantum Technology, Chalmers University of Technology, we are a research group working in the field of quantum optomechanics. We require a tunable laser operating in the range 1420nm to 1530nm. The laser would be used for broadband spectroscopic measurements with high spectral resolution, more specifically transmission spectra of Fabry-Perot-type optical microresonators and other integrated photonic devices, for example nanooptomechanical devices.
