Fiber lighting systems and methods of switching light are disclosed. A system includes a light source and a switching device having an input that receives light from the light source, at least one output, and a microelectromechanical mirror disposed in an optical pathway between the input and the output. The mirror is repositionable to direct light from the input into the output. The system also includes a light diffusing fiber coupled to the output that emits light along its length and an electronic control unit that directs the light source to pulse the light at a frequency of 10 Hz - 500 kHz and orient the mirror for directing the light to an output. The repositioning is synchronized with the pulsing such that the mirror is at a coupled orientation during a pulse and is repositioned between pulses.

Embodiments are directed towards a multi-stage wireless power transmission system that includes a transmitting unit and a receiving unit. The transmitting unit transmits a power beam to the receiving unit, which converts the power beam into local electrical power and provides it to a personal electronic device without a corded connection between the receiving unit and a mains power supply. The transmitting unit includes a light-based transmitter to generate and transmit a power beam towards the receiving unit. The receiving unit includes a receiver to receive at least a portion of the power beam and to convert the received power beam into local electrical power. The receiving unit also includes a power output unit to provide the received local power to a personal electronic device when the personal electronic device, which is separable from the receiving unit, is electrically coupled to the power output unit.

Provided is a laser light source apparatus with which it is possible to avoid the loss caused by excessive excitation of a solid-state amplifier when output of pulse light from the apparatus is temporarily stopped, and with which deterioration in the beam propagation properties immediately after output is restarted can be avoided. The laser light-source apparatus comprises: fiber amplifiers (20, 30) and a solid-state amplifier (50) which amplify the pulse light output from the seed light source (10) by gain switching; non-linear optical elements (60, 70) which perform wavelength conversion on pulse light outputted from the solid-state amplifier; a light-switching element (40) which allows or hinders the propagation of pulse light from the fiber amplifier to the solid-state amplifier; and a control unit (100) which controls the light-switching element (40) so as to hinder the propagation of light during output of pulse light from the seed light source (10) and allows the propagation of light while pulse light is not being output from the seed light source, thereby generating an output stopped state in which the output of pulse light from the optical elements (60, 70) is stopped.

摘要:
A laser source (10) for emitting an output beam (12) includes a first gain medium (16B) that generates a first beam (16A), a second gain medium (18B) that generates a second beam (18A), a common feedback assembly (28) positioned in the path of the first beam (16A) and the second beam (18), and a control system (32). The common feedback assembly (28) redirects at least a portion of the first beam (16A) back to the first gain medium (16B), and at least a portion of the second beam (18A) back to the second gain medium (18B). The control system (32) selectively and individually directs power to the first gain medium (16B) and the second gain medium (18). Additionally, the common feedback assembly (28) can include a feedback mover (46) that continuously adjusts the angle of incidence of the first beam (16A) and the second beam (18A) on the feedback assembly (28). Moreover, the control system (32) can selectively direct pulses of power to the gain mediums (16B) (18B) based on the position of the feedback assembly (28).
