A superalloy substrate, such as a turbine blade or vane, is fabricated or repaired by laser beam welding to clad one or more layers on the substrate. Laser optical energy is transferred to the welding filler material and underlying substrate to assure filler melting and adequate substrate surface wetting for good fusion. Energy transfer is maintained below a level that jeopardizes substrate thermal degradation. Optical energy transfer to the filler and substrate is maintained uniformly as the laser beam and substrate are moved relative to each other along a translation path by varying the energy transfer rate to compensate for localized substrate topology variations.

The invention discloses a donor-acceptor distance distribution measuring method based on fluorescence correlation spectroscopy. Fluorescent labeled living cells of donors and acceptors are subjected to a selective donor excitation operation through a fluorescence correlation spectroscopy module of a laser scanning confocal microscope in different laser power. A correlation card acquires photon number fluctuation signals of a donor channel and an acceptor channel to form a self-correlation curve. Energy transfer rate and energy transfer efficiency can be calculated through triplet state analysis of the self-correlation curve of the acceptors. In addition, triplet state distribution of the energy transfer rate and the energy transfer efficiency can be inverted from the self-correlation curve of the triplet state of the acceptors through a maximum entropy algorithm so that donor-to-acceptor distance distribution can be calculated. A fluorescence correlation spectrum analysis method itself is an excellent technology of measuring concentration of a dilute solution, so that the measuring method can be used for measuring donor-acceptor non-paired fluorescence resonance energy transfer efficiency and donor-acceptor non-paired distance distribution after integration items of overlap items of the spectrum being corrected with respect to the donor-acceptor concentration proportion. The measuring method is convenient to use and high in measuring precision.
