In a semiconductor lasers using quantum well gain medium, a quantum well stack is mounted in an epi-down configuration. The epitaxial side of the device may be directly bonded to an efficient heat transport system so that heat may more easily leave the quantum well stack layers and be disposed at a heatsink. Such a device runs cooler and exhibits reduced loss mechanisms as represented by a laser system loss-line. External cavity systems using this configuration may permit a high degree of tunability, and these systems are particularly improved as the tuning range is extended by lowered cavity losses.

An imaging system () for imaging an emitting gas () includes an imager () and a laser source (). The imager () captures an image () of light in the mid-infrared (MIR) range. The laser source () includes a semiconductor laser () that directly emits an output beam () that is in the MIR range. The output beam () may be adapted to backscatter near and/or be absorbed by the emitting gas (). Thus, when an emitting gas () is present, the gas () may absorb and attenuate the backscattered light. As a result thereof, a shadow or contrast (A) corresponding to the emitting gas () may be visible in the image () that is captured by the imager ().
