摘要： All-optical quasi-phase matching (QPM) uses a train of counterpropagating pulses to enhance high-order harmonic generation (HHG) in a hollow waveguide. A pump pulse enters one end of the waveguide, and causes HHG in the waveguide. The counterpropagation pulses enter the other end of the waveguide and interact with the pump pulses to cause QPM within the waveguide, enhancing the HHG.

摘要： Apparatus and methods for self-cleaning of optical elements in sealed environments over a wide range of operating optical frequencies prevent long-term power degradation by introducing low-pressure backfill of a reactive gas such as oxygen into a vacuum chamber containing the optical elements. The backfill pressure is preferably between 10−4 torr and 10 torr, and generally between 0.1 torr and 2 torr at room temperature. The vacuum chamber may be continuously evacuated and backfilled, or may be sealed after evacuation and backfill is performed.

摘要： An autonomous golf ball picking system configured to pick up golf balls from an outdoor environment. The system includes a route map defining a path to pick up golf balls from the ground. The route map is in a computer readable format. An unmanned ground vehicle having a base unit having an internal ball retention compartment, a ball picking roller configured to pick up golf balls from the ground and to deposit the picked-up golf balls into the internal ball retention compartment, at least two linked wheels, each of the at least two linked wheels driven by an independent motor and configured to move the unmanned ground vehicle around the ground, a battery to provide power to the unmanned ground vehicle, and an unmanned ground vehicle computer system. The computer system is capable of reading the route map and sending directional instructions to the independent motors in order to drive the unmanned ground vehicle along the path set out according to the route map. The system further includes a docking station configured to receive the unmanned ground vehicle upon completion of picking up golf balls according to the route map. The docking station having a golf ball receiving bin configured to receive the picked golf balls from the internal ball retention compartment and to recharge the vehicle's battery.
