Stability under changes of temperature and current increased. External etalon aligned with laser diode provides optical feedback enhancing stability of operation in one or few of longitudinal laser modes. Provides amount of feedback varying periodically with wavelength. Also helps to increase stability by reducing sensitivity to minor feedback from external objects other than etalon.
