摘要:
An unipolar organic injection laser in which electrically-stimulated intraband transitions result in lasing. An active region includes at least one organic injector layer and at least one organic emitter layer. Each organic emitter layer has a first energy level and a second energy level on a same side of an energy gap defined by a conduction band and a valance band. Charge carriers are injected through the organic injector layer into the first energy level of the organic emitter layer when a voltage is applied across active region. The difference in energy between the first and second energy levels produces radiative emissions when charge carriers transition from the first energy level to the second energy level. Population inversion is maintained between the first and second energy levels, producing stimulated emission and lasing.

A spa cover lift is provided that includes a movable frame adapted for pivotable attachment to the side of a spa, one or more struts for positioning the movable frame between extended and retracted positions with respect to the side of the spa, and apparatus for receiving a spa cover from the spa and retaining the cover adjacent the movable frame. The struts are operable to displace the movable frame to an extended position that is substantially coplanar with respect to the top surface of the spa to provide a surface onto which a spa user can slide a spa cover. The struts are further operable to displace the movable frame to a retracted position against the side of the spa for optimally storing the device along with the spa cover in a compact configuration when the spa is in use against the side of the spa.
