Special Notice: ENERGY, DEPARTMENT OF is offering a collaboration opportunity to further develop and commercialize a method for controlled etching of water sensitive optics. This method aims to remove surface defects and improve the laser-induced damage threshold of water-sensitive optical components. The invention utilizes water as an etchant, dispersed as nanosized droplets in a water-in-oil micro-emulsion, to effectively dissolve and etch the KDP crystal. The advantages of this method include controllable etching, improved damage threshold, applicability to any water-sensitive optical component, and the absence of toxic compounds. Lawrence Livermore National Laboratory (LLNL) has filed for patent protection on this invention and is seeking industry partners to bring it to the market. Interested companies should provide a statement of interest including company information, contact details, and a description of relevant expertise and facilities.
