An external-cavity tunable diode laser (ECTDL) is designed, which is based on a classical Littman-Metcalf structure. The diode laser with a wide gain spectrum is served as the seed source of the internal cavity. Meanwhile, the external-cavity feedback unit is composed of a blazed grating and a tuned...
