ABSTRACT:
Particular embodiments of the present invention relate generally to altering the effective conversion efficiency curve of an optical package employing a semiconductor laser and an SHG crystal or other type of wavelength conversion device. For example, according to one embodiment of the present invention, a method of controlling an optical package is provided where the optical package is tuned such that ascending portions of a transmission curve representing a spectral filter are aligned with descending portions of a conversion efficiency curve representing a wavelength conversion device. With the filter and wavelength conversion device so aligned, the optical package is further tuned such that the wavelength of the fundamental laser signal lies within a wavelength range corresponding to aligned portions of the ascending and descending portions of the transmission and conversion efficiency curves. Additional embodiments are disclosed and claimed.
