datasheet
nanoplus 12.5 μm DFB quantum cascade lasers show unique device performance to meet the
requirements of our customers. Their high side mode supression ratio (SMSR) and high spectral
purity make them perfectly suited for aplplications like e.g. gas sensing. The devices work in pulsed
mode at operation temperatures up to 250 K.
