Measurement of the emission spectrum of a semiconductor laser using laser-feedback interferometry. [PDF]
The effects of optical feedback (OF) in lasers have been observed since the early days of laser development. While OF can result in undesirable and unpredictable operation in laser systems, it can also cause measurable perturbations to the operating ...
