Abstract

Continuous-wave operation of an external cavity quantum-cascade laser on a thermoelectric cooler is reported. The active region of the gain element was based on a bound-to-continuum design emitting near 5.15 µm. The external cavity setup was arranged in a Littrow configuration. The front facet of the gain chip was antireflection coated. The laser could be tuned over more than 170 cm^−1 from 4.94 to 5.4 µm and was single mode over more than 140 cm^−1. The output power was in excess of 10 mW over ∼100 cm^−1 and in excess of 5 mW over ∼130 cm^−1 at −30°C.
