description specifications * 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.
