Research on Spectroscopy Modulation of a Distributed Feedback Laser Diode Based on the TDLAS Technique
Laser current and temperature control circuits have been developed for a distributed feedback laser diode, which is applied as the light source of a tuneable diode laser absorption spectroscopy system. The laser’s temperature fluctuation can be limited within the range of −0.02 to 0.02°C, and good o...
