Abstract
Apparatus and methods that provide a tunable laser output wavelength which varies linearly or with high predictability over time, and which can provide tuning speeds of greater than 100 nanometers per second. The apparatus includes a laser resonator cavity having first and second reflective elements, at least one of which is movable to provide a constant change in output wavelength with respect to time. A tuning assembly associated with the movable reflective element is structured, configured, and positioned to adjust the movable reflective elements such that constant changes in output wavelength and high tuning speeds are provided.
