IR Laser System for generating tuneable wavelength of light between 1.5 – 3.5 µm

The procurement contact named on the official notice.

The DIAL team are looking to procure a new and upgraded IR laser system to replace their aging unit.

The pump laser will be a seeded flashlamp pumped laser with pulse duration of 9 ns and line width 0.003 cm-1, it will be capable of simultaneously emit the fundamental and second harmonic at a repetition rate of 20 Hz.

The pulse energy in the IR should be around 700 mJ and 400 mJ in the green.

The system needs to be capable of outputting a total wavelength range between 1.5 – 3.5 µm.

Obtaining the tuneability utilising a dye laser and a two-stage non-linear mixing component.

The system should be designed in such a way that the wavelength can be switched between two wavelengths at a frequency of greater than (or equal to) 5 Hz.

Any wavelength drift must be minimal and easily corrected by a competent operator.

The system should be fully integrated, and installed subject to a site acceptance test at NPL’s facility.

NPL expect the system to be maintained by the supplier on an ad hoc basis and serviced by the supplier annually.
