| This paper used LIBS, followed by Laser Induced Fluorescence to measure P in Steel samples. After experimentation, the LIF laser at 255.49nm proved the best for excitation of P (without also pumping Fe transitions). Experiments exploring the relationship between pump laser energy and wavelength showed better results for 532nm (over 1064nm), with increasing P signal with increasing energy. In contrast, increasing the probe laser energy provided no significant increase in signal above 1mJ/cm^2. | |||||
