Photovoltaic devices and methods for fabricating a photovoltaic devices. The method includes applying a coating layer that surrounds each of a plurality of silicon particles. The method also includes implanting the plurality of silicon particles into a substrate layer such that an exposed portion of each of the plurality of silicon particles extends away from a surface of the substrate layer. The method further includes removing a portion of the coating layer that is positioned around the exposed portion of each of the plurality of silicon particles. The method also includes placing an insulator layer on the surface of the substrate layer. The method further includes placing a selective carrier transport layer on the exposed portion of each of the plurality of silicon particles.

An optical parametric oscillator includes one unidirectional enhancement resonator for optical pump-radiation and a second unidirectional resonator at least partially coaxial with the enhancement resonator. An optically nonlinear crystal is located in the coaxial portion of the resonators and converts the optical pump-radiation to signal radiation having a wavelength longer than that of the pump radiation and idler radiation having a wavelength longer than that of the signal radiation. The second resonator resonates the signal-wavelength radiation and delivers a fraction of that radiation as output radiation.

A hybrid CW MOPA includes an OPS-laser resonator delivering radiation in a plurality of longitudinal lasing-modes or wavelengths. The multiple longitudinal mode output is amplified in a fiber-amplifier. Amplified lasing-modes from the fiber-amplifier are frequency-converted by an optically nonlinear crystal in a ring-resonator having the same length as the laser resonator, such that the ring-resonator is resonant for all of the amplified lasing-modes.

A method of forming a dielectric film that includes nitrogen. The method includes incorporating nitrogen into a dielectric film using a nitridation gas and a rapid thermal annealing process, wherein an ultra-low pressure of equal to or less than about 10 Torr is used for the rapid thermal annealing process.

A method for detecting trace evidence materials on a surface comprises irradiating the surface with radiation from two or more lasers emitting radiation at different wavelengths selected to stimulate luminescence in the trace materials. The evidence is detected by observing the surface through an optical filter arranged to transmit the luminescence, while blocking transmission of the laser radiation wavelengths reflected or scattered from the surface.
