Statement of Work/Need
BACKGROUND:
National Institute of Standards and Technology (NIST) has launched an ambitious program in laser funding with Strategic Emerging Research Initiative funds from the NIST Director. The goal of this program is to elucidate the fundamental laser-matter interaction that occur in advanced commercial laser processing techniques including laser welding. It is NIST’s responsibility in this program to develop in situ process monitoring tools that are capable of gathering real-time information about the laser welding process. This information is to be combined with mechanical weld testing to facilitate a deeper understanding of the laser welding process, which will eventually allow for optimization of the laser welding process. NIST has identified laser-induced fluorescence spectroscopy as a viable route to achieve NIST’s stated goals.
PURPOSE:
In order to perform fluorescence spectroscopy a particular laser source is needed. The laser necessary for these experiments must meet strict requirements for wavelength tunability, bandwidth, narrowness of wavelength linewidth, high output energy, physical size, and design flexibility. The item described in this purchase has been identified as necessary to further our research effort for advancing laser welding understanding.
TECHNICAL SPECIFICATION
The supply contract is for a brand name item. The equipment has been identified as being suitable for the intended application. Specifications for the laser system are provided below. The pump laser (item #2 below) must be purchased with the OPO as they are designed to work as a system and are optimized together.
