摘要： A laser gyroscope is formed as a sealed, unitary assembly of mirrors optically contacted to a monolithic gyro block without any means, such as Brewster windows, for isolating the laser plasma from any of the mirrors. The mirrors are fabricated with hard multilayer dielectric films which can withstand plasma exposure. A magnetic mirror utilizing the transverse Kerr effect to separate the frequencies of counter-propagating beams, and to avoid lock-in, includes a Ni-Fe alloy layer over which is directly deposited a thin iron or iron alloy layer to form a rotationally switchable Kerr effect combination. The magnetic field for switching is generated by an electric current developed in two pairs of orthogonally disposed wires embedded in the substrate immediately below the iron and Ni-Fe alloy layers. A specially designed multilayer dielectric stack is disposed on one of the mirrors, for example over the iron and Ni-Fe alloy layers on the magnetic mirror, and is configured to suppress S mode oscillation in order to limit the gyro to P mode operation.
摘要翻译：形成激光陀螺仪作为密封的单一组件的反射镜，其与诸如布鲁斯特（Brewster）窗口无任何方式光学接触单片陀螺仪块，用于将激光等离子体与任何反射镜隔离。反射镜由可以承受等离子体暴露的硬质多层介质膜制成。利用横向克尔效应来分离反向传播光束的频率并避免锁定的磁镜包括Ni-Fe合金层，在其上直接沉积薄铁或铁合金层以形成可旋转切换的克尔效果组合。用于切换的磁场由在正下方的铁和Ni-Fe合金层内嵌入基板中的两对垂直布置的电线产生的电流产生。特别设计的多层电介质叠层设置在一个反射镜上，例如在磁反射镜上的铁和Ni-Fe合金层上，并且被配置为抑制S模式振荡，以将陀螺仪限制为P模式操作。

摘要： A ring laser gyroscope incorporates a resonant cavity generally shaped as an irregular pentagon having a portion thereof conformed as three legs of a rectangle closed by two symmetrical other legs to form an apex. As result the enclosed area is increased, increasing sensitivity and decreasing lock-in, while magnetic effects are reduced. Additionally, the irregular shape allows for the extension of the gain medium which therefore increases the effectiveness thereof.
