    Abstract: A direct metal laser melting (DMLM) system includes a laser device configured to generate a melt pool in a powder bed based on a build parameter. In addition, the DMLM system includes a confocal optical system directed at the melt pool and configured to receive an optical signal emitted by the melt pool. The DMLM system further includes an optical sensor operatively coupled to the confocal optical system that is configured to receive the optical signal and to generate an electrical signal in response to the optical signal. A computing device is configured to receive the electrical signal from the optical sensor and to generate a control signal in response. The control signal is configured to modify the build parameter of the direct metal laser melting system in real-time to adjust at least one of a melt pool size and a melt pool temperature to achieve a desired physical property of the component.

    Abstract: A method of monitoring a surface temperature of a hot gas path component includes directing an excitation beam having an excitation wavelength at a layer of a sensor material composition deposited on a hot gas path component to induce a fluorescent radiation. The method includes measuring fluorescent radiation emitted by the sensor material composition. The fluorescent radiation includes at least a first intensity at a first wavelength and a second intensity at a second wavelength. The surface temperature of the hot gas path component is determined based on a ratio of the first intensity at the first wavelength and the second intensity at the second wavelength of the fluorescent radiation emitted by the sensor material composition.
