Abstract
Techniques are disclosed relating to gas leak detection. The techniques can be deployed, for example, in compact, handheld portable devices usable for detecting leaks in space-confined applications. The devices generally include an unstablized laser and thermal imaging camera that allow for detection of gas that absorbs at least some of the wavelength of operation of the unstablized laser. The devices can be operated at a low-power density for safety and/or may be configured to mitigate wavelength hopping associated with unstablized laser light sources.
