  • Patent number: 8890025
    Abstract: A method of laser scribing a CdTe solar cell structure includes providing a laser operable to produce an optical pulse. The optical pulse is characterized by a temporal profile having a first power level during a first portion of the optical pulse and a second power level less than the first power level during a second portion of the optical pulse. The method also includes directing the optical pulse to impinge on the CdTe solar cell structure. The CdTe solar cell structure includes a substrate, a transmission spectrum control layer adjacent the substrate; a barrier layer adjacent the transmission spectrum control layer, and a conductive layer adjacent the barrier layer. The method further includes initiating a removal process for the conductive layer and terminating the removal process prior to removing the barrier layer.

  • Patent number: 8847112
    Abstract: A series of laser pulses in a pulse train, each pulse with a beneficial temporal power shape instead of the conventional laser temporal power shape, scribes a line in a thin film of material on a substrate. The beneficial temporal pulse shape has a spike/plateau chair shape or a square pulse shape. Scribing a line in the thin film is achieved by placing the series of laser pulse spots on the line to be scribed such that there is an overlapping area between adjacent laser pulse spots along the line. The use of a series of laser pulses with beneficial pulse shape to scribe a line in the thin film results in a better quality and cleaner scribing process compared to that achieved with the conventional pulse shape.

  • Patent number: 8842362
    Abstract: A method of operating a fiber amplifier characterized by a spectral gain curve includes providing an input signal at a signal wavelength. The signal wavelength lies within an in-band portion of the spectral gain curve extending from a first in-band wavelength to a second in-band wavelength, the in-band portion being characterized by a first amplitude range. The method also includes providing pump radiation at a pump wavelength. The pump wavelength is less than the signal wavelength. The method further includes coupling the pump radiation to the fiber amplifier and amplifying the input signal to generate an output signal. All portions of the spectral gain curve at wavelengths less than the first in-band wavelength and greater than the pump wavelength are characterized by a second amplitude less than or equal to 10 dB greater than the first amplitude range.
