• Provide a gas-free environment in which the laser pulse can be focused onto a target.
• The target chamber has many portholes which can be used for beam input/output or modular diagnostic equipment.
• The target chamber usually supports a high vacuum but can sometimes be pressurized with a buffer gas.
