Patent abstract
An external cavity diode laser may have an output wavelength that is tuned by an end mirror mounted on an element having a flexure hinge. The flexure hinge may be designed to exhibit a stationary pivot point over a desired tuning range, and may allow the external cavity to be tuned without the laser hopping between longitudinal modes. Chromatic dispersion of the laser medium may be accommodated by adjusting a distance between a laser diode and a grating included within the external cavity. The position may be adjusted to find an operating configuration which allows mode-hop-free tuning over the entire desired tuning range.
