A method for controlling the deposition of vaporized organic material onto a substrate surface, includes providing a manifold having at least one aperture through which vaporized organic material passes for deposition onto the substrate surface; and providing a volume of organic material and maintaining the temperature of such organic material in a first condition so that its vapor pressure is below that needed to effectively form a layer on the substrate, and in a second condition heating a volume percentage of the initial volume of such organic material so that the vapor pressure of the heated organic material is sufficient to effectively form a layer.

Controlling the vaporization of organic material

A method for controlling the deposition of vaporized organic material onto a substrate surface, includes providing a heating device to produce vaporized organic material; providing a manifold having at least one aperture through which vaporized organic material passes for deposition onto the substrate surface; providing a controller operating independently of the heating device and effective in a first condition for limiting the passage of vaporized organic material through the aperture, and effective in a second condition for facilitating the passage of vaporized organic material through the aperture; and wherein the heating device, or the controller, or both are contiguous to the manifold.

Method for controlling the deposition of vaporized organic material

A method for thermally stabilizing an optical parametric oscillator (OPO)to maintain constant optical path length for stable high power output places a beam dumpoutside an OPO cavity. The OPOhas a nonlinear crystalwithin cavityfor splitting a single input pump beaminto lower energy signal and idler beams. The method includes providing a cavity exit port for unconverted pump and generated idler beams, and absorbing unconverted beams in beam dump. The method includes athermalization by actively cooling surfaces used as an optics mounting base, and athermalization by constraining the size of cavityby using thermally stiff members, guiding pins or rails, or by using bimetallic materials with different expansion.
