Tunable extended-cavity diode laser based on a novel flexure-mechanism

This article presents the design, implementation and characterization of an extended-cavity laser diode. The design of the wavelength tuning mechanism is based on a two degrees-of-freedom monolithic flexure-based mechanism. The linear stroke for cavity length tuning could be minimized by optimizing the position of the prism's. The tuning with narrowband emission line is demonstrated in the wavelength range of 837 nm to 870 nm.
