Patent number: 10180397Abstract: A THz quantum cascade laser is used to investigate a target by directing a first beam of laser radiation from the laser at the target to thereby produce a second beam of laser radiation by interaction of the first beam with the target. Self-mixing of the first and second beams occurs within the laser and causes variations in a signal such as the operating voltage of the laser. An operating parameter of the laser that affects the interaction of the first beam with, the target is varied.
