摘要： A laser system involving coupled distributed resonators disposed serially, with the lasing gain medium located in the main resonator and the output of that resonator being directed into a free space resonator, such that the main resonator output mirror is effectively the free space resonator. The distributed resonators end mirrors are retroreflectors. Interference occurs between light traveling towards the remote mirror of the free space resonator and light reflected therefrom, generating regions of high reflectivity. The coupling of the free space resonator to the regions of high reflectivity of the free space resonator enables the first resonator to lase efficiently, even though the true reflectivity of the main resonator output mirror outside of those regions is insufficient to enable efficient lasing, if at all. This coupled resonator structure enables lasing to occur with a high field of view and the high gain engendered by the high reflectivity regions.

摘要： A system for transmission of power into a space, comprising one or more transmitters and several portable receivers which can receive power transmitted. Receivers can transmit data back to transmitters regarding their power needs, based on the state of charge of their batteries. A transmission protocol exists whereby each transmitter can detect legitimate receivers within its field of view and transmit a first amount of energy to any such receiver, which may report receiving that energy back to a transmitter, together with data relating to its power needs. Transmitters can deny power transmission to some receivers based on the data received from a reporting receiver. The first amount of energy transmitted may be used to power up a sleeping receiver, before transmission of useful amounts of power, if allowed by the protocol. Other aspects of the transmission protocol relate to the division of available power between requesting receivers.
摘要翻译：一种用于将功率传输到空间中的系统，包括一个或多个发射机和可接收发射功率的几个便携式接收机。接收机可以根据电池的充电状态将数据发送回发射机，以了解电力需求。存在一种传输协议，其中每个发射机可以检测其视野内的合法接收机，并将第一数量的能量发送到任何这样的接收机，这些接收机可以将接收到该能量的报告连同其功率需求相关的数据报告给发射机。发射机可以基于从报告接收机接收到的数据来拒绝对某些接收机的电力传输。如果协议允许，则在发送有用量的功率之前，所传输的第一能量可以用于为睡眠接收机加电。传输协议的其他方面涉及在请求接收者之间划分可用功率。

摘要： A system for optical wireless power transmission to a power receiving apparatus generally situated in a mobile electronic device. The transmitter has an optical resonator with end reflectors and a gain medium positioned between them, such that an optical beam is generated. The frequency of the beam is selected such that it is absorbed by almost all transparent organic materials in general use. A beam steering unit on the transmitter can direct the beam in any of a plurality of directions, and the beam is absorbed on the receiver by means of an optical-to-electrical power converter, through a low reflection surface. The band gap of this power converter is selected to be smaller than that of the gain medium. The receiver has a voltage converter including an inductor, an energy storage device and a switch. A beam steerer controller ensures that the beam impinges on the receiver.

摘要： A receiver for receiving an incident beam of optical power from a remote transmitter over a predefined field of view, comprising an input lens having a high durability coating that can withstand domestic handling and contamination. Such a high durability coating may reflect a non-insignificant part of the light incident thereon. Behind the lens, there is fitted a retroreflector disposed such that it reflects that part of the incident beam traversing the lens, back through the lens to the transmitter. Reflections from the front surface of the lens impinge on one or more transparent beam catchers appropriately located, and equipped with energy conversion devices, such as photovoltaic cells, to convert light from the reflections of the incident beam into electricity. Additional energy conversion devices may be located inward of the lens, to collect and convert reflections from the inner surface of the lens, of light returning from the retroreflector.

摘要： A receiver for receiving an incident beam of optical power from a remote transmitter over a predefined field of view, comprising a transparent or semi-transparent front surface window adapted to allow transmission therethrough of light of the beam coming from a field of view of the remote transmitter, and configured to have mechanical durability selected to withstand a predetermined level of handling. The receiver has a retroreflector with a size such that it is operative over only a substantially small part of the area of the beam of optical power incident on the front surface window, the retroreflector being adapted to return a portion of the incident beam of optical power to generate a feedback signal to enable lasing to commence, The receiver also has a photovoltaic cell shielded from the user by the front surface window, and adapted to absorb the beam and to convert it to electrical power, and in addition, a marker for detection and identification of the receiver. The pupil of the retroreflector is adapted to be at or close to the front surface window.
