Systems provide cooling of an optic such as an optically addressed light valve such that the valve is sensitive to temperature and pressure variations and is thus temperature and pressure controlled. In the case of an optic such as an optically addressed light valve, the fluid pressure outside the valve is low enough that it does not compress the liquid crystal gap of the valve. The cooling fluid is transparent to the high powered wavelength of light used during operation such as in an additive manufacturing process.
