    • An optical power beam transmission systems, with a directional light transmitter and receiver. The transmitter contains an amplifying laser medium, and this together with a retroreflector in the receiver, forms a laser resonator. When lasing sets in, the receiver can extract optical power through an output coupler and convert it to electrical power. The gain medium may be a disc having a thickness substantially smaller than its lateral dimensions. The laser resonator is operated as a stable resonator to ensure safe operation. This is achieved by use of an adaptive optical element, for reducing the diameter of the energy beam impinging on the gain medium, thereby increasing the overlap between the energy beam and the gain medium. As the transmitter-receiver distance is changed, such as by movement of the receiver, the adaptive optical element focal length changes to ensure that the cavity remains within its stability zone.
    • 光功率光束传输系统,带有定向光发射器和接收器。 发射机包含放大激光介质,并与接收机中的后向反射器一起形成激光谐振器。 当激光投射时,接收器可以通过输出耦合器提取光功率并将其转换为电能。 增益介质可以是具有基本上小于其横向尺寸的厚度的盘。 激光谐振器作为稳定的谐振器运行,以确保安全运行。 这通过使用自适应光学元件来实现,用于减小入射到增益介质上的能量束的直径,从而增加能量束和增益介质之间的重叠。 随着发射器 - 接收器距离的改变,例如通过接收器的移动,自适应光学元件焦距变化,以确保空腔保持在其稳定区域内。

    • A laser designed to emit a pulsed beam of short wavelength comprises two bodies of nonconductive material within a cylindrical housing, at least one of these bodies being a flat ceramic disk with a high dielectric constant. A narrow interspace between the two bodies is occupied by two coplanar metal layers with confronting rectilinear edges forming an elongate excitation cavity between them, these layers being galvanically interconnected through an inductance and constituting a pair of capacitors with a common metal layer on the opposite face of the ceramic disk. One of the coplanar layers is connected to a source of high potential, the other of these layers being intermittently energizable by a generator of trigger pulses to excite a gas filling the elongate cavity.
    • 设计成发射短波长脉冲光束的激光器包括在圆柱形壳体内的两个非导电材料体,这些主体中的至少一个是具有高介电常数的平坦陶瓷盘。 两个物体之间的窄间隙由两个共面的金属层占据,相对的直线边缘在它们之间形成细长的激发腔,这些层通过电感电流互连,并在相对的表面上形成具有公共金属层的一对电容器 陶瓷盘。 共面层之一连接到高电位源,这些层中的另一层由触发脉冲发生器间歇地激励,以激发填充细长腔的气体。
