2.0 μm DFB laser diodes (in the following a 2004nm device is exemplary presented) show
unique device performance to meet the requirements of our customers.
Their high side mode suppression ratio (SMSR) and high spectral purity make them
perfectly suited for applications like e.g. CO2 spectroscopy. Mode-hop free DFB emission
with a high side mode suppression ratio (SMSR) around 35dB is guaranteed for the
device in the entire specified temperature and current range of operation.
