Abstract:
A system incorporating safety features, for optical power transmission to receivers, comprising an optical resonator having end reflectors and a gain medium, a driver supplying power to the gain medium, and controlling its small signal gain, a beam steering apparatus and a controller to control at least the beam steering apparatus and the driver. The controller responds to a safety risk occurring in the system, by outputting a command to change at least some of the small signal gain of the gain medium, the radiance of the optical beam, the power supplied by the driver, the scan speed or the scan direction and position of the beam steering apparatus, or to register the scan pose which defines the location of said optical-to-electrical power converter. The controller may also ensure a high overall radiance efficiency, and may warn of transmitted power not received by a targeted receiver.

Claim (Index 15):
A system for optical wireless power transmission to at least one power receiving apparatus, said system comprising:\n an optical resonator having end reflectors and adapted to emit an optical beam; a gain medium comprising either a semiconductor device or a solid host doped with Neodymium ions and in optical communication with a filter attenuating radiation for at least one frequency having a wave number in the range 8,300 cm \u22121  to 12,500 cm \u22121 , said gain medium being positioned inside said optical resonator and having a first bandgap energy, said gain medium being thermally attached to a cooling system and configured to amplify light passing through it; a driver configured to supply power to said gain medium, and enabling control of the small signal gain of said gain medium; a beam steering apparatus configured to direct said optical beam in at least one of a plurality of directions; an optical-to-electrical power converter located in said at least one power receiving apparatus, and configured to convert said optical beam into electrical power having a voltage, said optical-to-electrical power converter having a second bandgap energy; a detector configured to provide a signal indicative of said optical beam impinging on said optical-to-electrical power converter; a voltage converter connected to the output of said optical-to-electrical power converter, said voltage converter comprising an inductor having an inductance between L = 1 1.28 * 10 - 40 * f * E gain 2 * 1 - E gain 5 * 10 - 19 * V output P laser driver \ue89e \ue89e and L = 1 3 * 10 - 38 * f * E gain 2 * ( 1 - E gain 4 * 10 - 20 * V output ) P laser_driver where f in the switching frequency measured in Hertz, E gain  is the bandgap energy of the gain medium measured in Joules, V output  is the output voltage of the DC/DC converter in volts and P laserdriver  is the power measured in watts, supplied to the gain medium by the laser driver; and a controller adapted to control at least one of the status of said beam steering apparatus and said driver, said controller receiving a control input signal at least from said detector, wherein said controller is configured to respond to an indication of a safety risk occurring in the system, by outputting a command to result in at least one of:\n causing said driver to change the small signal gain of the gain medium; \n changing the radiance of said optical beam; \n changing the power supplied by said driver; \n changing the scan speed of said beam steering apparatus; \n changing the pose of said beam steering apparatus; and \n recording the scan pose which defines the location of said optical-to-electrical power converter.
