Tunable lasers have played an important role in a variety of industrial fields, by supplying stable output over a wide range of wavelengths. The external-cavity diode laser (ECDL) is widely used, because it provides a relatively broad tuning range, compact configuration, and easy control. In this paper, a new design is proposed for the Littman ECDL. The new design possesses a mode-hop-free single mode which is capable of tuning over a wide range of 17 nm, as a result of reconfiguring the pivot point location. Simulation and experimental studies were performed to verify our proposed method.
