Paper Abstract
Temperature effects on the spectral lines of two Fabry-Perot GaN-based blue laser diodes obtained from Toptica and Roithner Laser Tech are experimentally investigated over the temperature range 5 °C to 60 °C in steps of 0.5 °C. A high resolution monochromator SPEX 1403 with a nominal resolution of 0.003 nm is used in this study. A detailed comparison on the number of modes, mode spacing, emission range and change of emission wavelength per degree Celsius will be presented in this paper. The results of this comparison are used to investigate the suitability of the employment of these laser diodes in open-path detection of NO2 gas pollution.
