Description
The National Physical Laboratory [NPL] is the UK's National Measurement Institute and is heavily engaged in the research and development of novel measurement processes. The required femtosecond laser system will be used for precision machining of optical materials.
NPL require a femtosecond laser machining system to enable the fabrication of optical waveguides and microresonators at improved accuracies. The high pulse powers should allow for the direct machining of resonators via surface ablation as well as writing of resonators and waveguides inside the bulk of transparent materials via permanent localised refractive index changes (and possibly selective laser etching). Importantly, machining should be possible for a variety of material types - research shall be conducted with numerous crystalline and amorphous materials and the machining system should be flexible enough to allow accurate fabrication for each (materials include fused silica, CaF, Si3N4, and other transparent glasses).
Accordingly, NPL require a femtosecond laser system along with the means to direct this beam into the samples to be machined. Finally, a method to precisely move the sample around the focal spot of the beam is then required for the machining system. NPL understands that full machining systems may not be available, in which case a femtosecond laser will still be required with the remaining parts being assembled "in house".
