摘要： This invention provides a solution for operating a regenerative amplifier using a single electro-optical device, such as a Pockels cell. An efficient cavity geometry of a regenerative amplifier is provided for enabling pulse selection, coupling and releasing to an output by operating a single Pockels cell unit placed essentially in the middle of the optical cavity, between two polarizers, whereas a first polarizer is used for release of an amplified pulse and a second polarizer is used for injection of seed pulses and release of at least one of waste amplified pulses and seed pulses. One side of the cavity, with respect to the location of said Pockels cell, includes an empty space, whereas the other side is provided with a gain medium, which is pumped by a pump source. The regenerative amplifier of such optical design is both efficient and cost effective. The single electro-optical unit works both as the control unit for operating the regenerative amplifier and as an output pulse picker unit.

摘要： A slab laser and its method of use for high power applications including the manufacture of semiconductors and deposition of diamond and/or diamond-like-carbon layers, among other materials. A lamp driven slab design with a face-to-face beam propagation scheme and an end reflection that redirects the amplified radiation back out the same input surface is utilized. A side-to-side amplifier configuration permitting very high average and peak powers having scalability is also disclosed. Cavity filters adjacent to pump lamps convert the normally unusable UV portion of the pump lamp spectrum into light in the absorption band of the slab laser, thereby increasing the overall pump efficiency. The angle of the end reflecting surface is changed to cause the exit beam to be at a different angle than the inlet beam, thereby eliminating the costly need to separate the beams external to the laser with the subsequent loss of power.

摘要： A light emitting apparatus of the present invention includes: an EL emitting unit including at least a light emitting layer which generates an EL light; and a pair of light blocking layers arranged such that they sandwich the light emitting layer so that the layers block the EL light generated in the light emitting layer and that the EL light is radiated only from the end of the light emitting layer; and a light emitting unit which optically guides the EL light radiated from the end of the light emitting layer and emits a light having a wavelength equal to or different from that of the EL light. The EL light is emitted only from the end of the light emitting layer since the EL light generated in the light emitting layer is blocked by the pair of light blocking layers. This emitted EL light is optically guided by the light emitting unit and emitted as it is or a light having a different wavelength from the EL light.

摘要： The present invention provides a solar-pumped active device which utilizes a holographic antenna grating on a solar energy silicon substrate to select specific diffracted wavelength and couple pump wavelength in an approximately vertical way and converge the pump wavelength to excite an optical gain medium so that an optical amplifier or a laser can be obtained. The present invention requires no big size and is flexible over the surface shape and is suitable for free space optical communications on the ground and satellite optical communications. It means that the holographic antenna grating can be applied on the top floor of a building or on the glass surface of an outer wall. If it is applied to a satellite, the present invention can be deposited on a solar energy cell substrate to form a high optical amplification so that not only the electricity required in satellite optical communications can be reduced, but also a high-speed and large capacity of data can be transferred between satellites.
