Abstract: An athermal locking mechanism apparatus for large optic mounts is disclosed. The apparatus comprises at least one locking nut, at least one flexurized spring collet attached to a rigid base structure, a pivot shaft engaged with an optical yolk on a rotational axis of symmetry and a plurality of threads that joins the locking nuts with the flexurized spring collet The threads provide an increased level of a radial clamping force onto the pivot shaft, The interference generated between the locking nut and the spring collet causes all flexures to squeeze down onto the shaft, applying a purely symmetric radial force during the locking process. This eliminates any induced rotational torque and prevents the optical element from moving during the locking process after being properly aligned.

Abstract: Techniques and architecture are disclosed for controlling the temperature of a fiber laser system. In some embodiments, a single thermoelectric cooler (TEC) may be utilized to control the temperature of multiple system components. In some embodiments, a TEC may be physically/thermally coupled to a laser diode, which in turn may be physically/thermally coupled with a mounting plate to which one or more fiber grating holders are physically/thermally coupled, and an optical fiber that is operatively coupled with the laser diode may be physically/thermally coupled with the one or more fiber grating holders. In some embodiments, this may provide a thermal pathway/coupling between the optical fiber (e.g., its fiber grating(s)), and the TEC. In some embodiments, this may reduce/minimize the quantity of temperature control components, reduce system size/complexity, increase system dependability, and/or increase system performance/efficiency. Numerous configurations and variations will be apparent in light of this disclosure.
