Evaluation of a Laser Diode for DGV Application Available to Purchase

This paper will present the evaluation of a 300 mw, continuous wave, laser diode system which appears to be suitable for DGV use. The laser frequency range is sufficiently narrow and the lasing frequency can be adjusted across the range of the iodine reference cell (absorption line filter). A spectrum analyzer is used to document the frequency content of the laser across the frequency range of the iodine reference cell. The response of the iodine reference cell to the laser across its spectrum is measured at several iodine reference cell temperatures. The beam profile is also measured. This set of data determined the applicability of this laser for DGV use.
