Latest Patents

One of Wellman's latest patents is for a cooled laser mirror having adaptive flow control. This invention features an adaptive flow-control regulator that manages the circulation of cooling fluid through a cooled laser mirror. The regulator employs a temperature-sensitive spring to control the movement of a plunger in relation to an orifice, allowing for optimal cooling based on the temperature of the circulating fluid. As the temperature rises, the spring contracts, enabling a greater volume of coolant to flow, thus effectively dissipating heat from the mirror structure.

Another significant patent by Wellman involves fusible link actuators for deformable mirrors. This construction allows electrodistortive actuators to be mechanically fastened to the mirror's reflecting facesheet. The actuators can be disengaged by operating a fusible link, which can be made of thermoplastic material or an electrocapacitive layer. This innovative design enhances the functionality of deformable mirrors in various applications.
