摘要： A laser window is formed of spaced transparent strips with a high total surface area that lends itself to cooling by conduction heat transfer to metal channels between the strips. The metal channels carry either a fast flowing refrigerant or heat-pipe wick and fluid. One or both sides of the metal cooling channels can act as mirrors.

摘要： The mirror is constructed having a reflecting surface formed on a heat exchanger plate means having a manifold on each end. The free ends of the manifolds are connected by rod members. The plate means is bonded to the top of a rigid backing member and the bottom of the backing member is bonded at three points to a mounting pad member which in turn is mounted to a mount block by an alignment assembly at three locations. Each alignment assembly has interacting spherical and conical shaped members for facilitating installation. The mount block has three locations for receiving said assemblies, one location being rigid while the other two are located on flexible arms permitting a limited amount of movement to prevent an undue force being transmitted between the mount block and the backing member. The mount block is maintained on a foundation by a large bolt through the center thereof.

摘要： Optical mirrors are provided, particularly for use as lasercavity mirrors, including a face plate having an optically reflective surface in heat-exchanging relationship with coolant passages in which the flow of coolant in adjacent coolant passages is preferably counter-current in order to cool the optically reflective surface in a thermally balanced manner. Coolant is distributed to and collected from the coolant passages in the face plate by a first manifold plate. The first manifold plate has coolant distribution and collection passages for distributing coolant to and collecting coolant from the coolant passages in the face plate and manifold means for receiving and distributing coolant to each of the coolant distribution passages in the first manifold plate. The coolant collected by the coolant collection passages in the first manifold plate is distributed to coolant collection passages formed in a second manifold plate. Manifold means in the second manifold plate are provided for receiving coolant from each of the coolant collection passages in the second manifold plate and for conducting the coolant exteriorly of the mirror.

摘要： A system provides for a way for cooling an optical fiber. The system includes a coolant and a conduit. The conduit allows the coolant to flow through the conduit. At least part of the fiber passes through the conduit allowing the coolant to flow around the at least part of the fiber. In some configurations, the fiber runs parallel to the conduit. The system can include a pump diode that is part of an optical laser connected to an end of the fiber. The optical laser can further include a high reflector connected to the fiber and a partial reflector connected to the fiber to reflect some light back and forth between the high reflector and the partial reflector.

摘要： A compact high power laser calibration and testing system includes an active intracavity laser system that amplifies the laser power by recycling photons through a thin disk gain medium that is positioned between two or more highly reflective mirrors. The system is configured for calibration and testing of the high power lasers and optics that can be inserted into or positioned at the end of the intracavity. In another embodiment, the system is configured for characterization of high power laser beam propagation in operation-relevant atmospheres. The intracavity high power laser beam is configured to simulate high power laser beams with orders-of-magnitude reduced size, weight and operation power for calibrating laser powers and testing optical components. In applications that require an extra small footing or high portability, thermal management systems are configured to absorb large amounts of heat from the system for fixed time durations with the use of exchangeable cartridges made of phase change materials. The portability of the invention can be further increased and the system footing can be decreased by powering the system with disposable or rechargeable battery cartridges that can be rapidly replaced.

The measurement unit measures an elapsed time from a final trigger at which a laser processing operation of the laser processing machine has stopped and no user operation is applied with respect to the laser processing machine. The control unit 10 stops the element units based on the elapsed time after the final trigger, when a condition specified for each of the element units is satisfied.
