The Vacuum Spatial Filter & Vacuum Cell designed for Pulsed Lasers and characterized with high peak power

Vacuum Spatial Filter (VSF), is a vacuumed borosilicate glass cell at which center lays titanium pinhole. Spatial filter, a usual technique used to improve laser beam quality by removing noise from laser beams and resulting a smooth intensity profile. Since pulsed lasers have much higher pike power, vacuum cell is the only alternative, therefore a microscope objective (used to use for CW lasers) cannot be used to focus pulsed laser beams in to a pinhole because of COD.

Geola Digital designs and manufactures Vacuum Cells, which are intended for pulsed laser application. The cells can be manufactured with pinhole at the center (VSF) or without pinhole inside the cell (VC).
