A system for laser processing, comprising:

• a plate assembly comprising a first plate, a second plate secured to the first plate, and a pressure chamber located between the first plate and the second plate, wherein:
• the plate assembly comprises one or more spacers and one or more fasteners;
• the one or more fasteners urge the first plate toward the second plate;
• and
• the one or more spacers are located between the first plate and the second plate and ensure that a gap of at least a selected distance is preserved between the first plate and the second plate;
• a connector extending into the pressure chamber and in fluid communication with the pressure chamber;
• and
• a fixture having a first end and a second end, wherein the first end is attached to the second plate of the plate assembly, the second end has a surface shaped to fit a part to be retained and laser processed, the surface has at least one opening, and the fixture has a conduit extending therethrough in fluid communication with the pressure chamber and the at least one opening.
