A wide variety of gas molecules exhibit characteristic absorption lines in the near infrared.

DFB lasers emitting at 3270 nm are e. g. suited for highly sensitive detection of small CH 4 con-centrations. For this application, highly stable laterally and longitudinally single mode lasers are required.
