Abstract
The wavelength spectrum of a Hitachi HLP 1400 laser diode has been measured in a variety of conditions. The diode has been found to emit on several longitudinal modes, with the most pronounced ones being approximately 1% of the main lasing mode. The modal structure was found to exist even up to + or - 100 Angstrom away from the main line, and no incoherent emission could be measured between the modes. High resolution scanning Fabry-Perot tests were performed to determine the main line bandwidth and to observe feedback effects. In the presence of feedback the diode spectrum was found to be unstable. Reasons for this behaviour are discussed and a system that can alleviate this problem is proposed.
