Abstract: Dermatological systems and methods for providing a therapeutic laser treatment wherein the duration of a therapeutic laser pulse is based on one or more determinations of a surface temperature of the skin during the delivery of the pulse. Initiation of the therapeutic laser pulse may be based on sensed skin temperature during a cooling of the skin prior to initiation of the pulse.

Abstract: Dermatological systems and methods for providing a therapeutic laser treatment of tissue having poor chromophore selectivity using a laser source having a grating element to provide laser light having reduced linewidth. In some embodiments, the linewidth is reduced by at least half compared to the linewidth that would be provided in a system without the grating filter element. The linewidth may be reduced in some cases to 500 GHz or less, 300 GHz or less, or 200 Hz or less.

Abstract: A technique employing volume conductive electrodes for the generation of linear or non-linear electric fields is provided for devices used in charged ion optics. A hollow cylinder of a conductive polymer, which is loaded with conductive carbon particles or inherently conductive, and which is used to improve the performance of a dual stage gridless reflectron. Instrumental resolution measurements comparing a conventional discrete ring reflectron with a hybrid polymeric/discrete ring validate the design.
