Bulk measurement of copper and sodium content in CuIn(0.7)Ga(0.3)Se(2) (CIGS) solar cells with nanosecond pulse length laser induced breakdown spectroscopy (LIBS)
Jeremy M. D. Kowalczyk, Jeffrey J. Perkins, Alexander DeAngelis +4
In this work, we show that laser induced breakdown spectroscopy (LIBS) with a nanosecond pulse laser can be used to measure the copper and sodium content of CuIn(0.7)Ga(0.3)Se(2) (…

Closed Form of the Biphoton K-Vector Spectrum for Arbitrary Spatio-Temporal Pump Modes
Jeffrey Perkins
A closed form solution is derived for the biphoton k-vector spectrum for an arbitrary pump spatial mode. The resulting mode coefficients for the pump input that maximize the probab…
