    • An optical resonator has an axial mode frequency tuning rate with respect to temperature matching the peak gain frequency tuning rate, so that mode hops are eliminated. The resonator contains a composite cavity consisting of a gain medium and free space. Preferably, the resonator is a single-frequency solid state laser containing a solid state gain medium defining a physical path length Lg. The optical cavity is defined by a high reflector and output coupler surrounding the gain medium and defining a physical cavity path length Lo. The high reflector and output coupler are mounted on a substrate so that Lo is temperature insensitive. Preferably, the substrate is a thermally insensitive material having a negligible coefficient of thermal expansion; for example, it may be Invar™, Super-Invar™, ULE™ Glass, Zerodur™, and fused silica. Alternately, the substrate is a thermally isolated material that is temperature controlled and insulated from the gain medium. When Lo=Lg, the axial mode tuning rate has a greater magnitude than the peak gain tuning rate. However, Lo/Lg is fixed and designed so that the axial mode tuning rate is identical to the peak gain tuning rate. In particular, L o L g = 1 - n g - ν m ⁡ [ ( n g - 1 ) ⁢ 1 L g ⁢ ⅆ L g ⅆ T + ⅆ n g ⅆ T ⅆ ν g ⅆ T ] . The laser preferably contains means for ensuring single-frequency operation. For a ring laser, it may include a magnet and half-wave plate inside the cavity, coupled with rod-shaped gain material with anti-parallel Brewster facets. For a non-planar ring oscillator, the purpose of the half-wave plate is instead served by the non-planar path. Alternately, the resonator is an optical parametric oscillator.
    • 光谐振器具有相对于与峰值增益频率调谐率匹配的温度的轴向模式频率调谐速率,从而消除模式跳跃。 谐振器包含由增益介质和自由空间组成的复合腔。 优选地,谐振器是包含限定物理路径长度Lg的固态增益介质的单频固态激光器。 光腔由围绕增益介质的高反射器和输出耦合器限定,并且限定物理空腔路径长度Lo。 高反射器和输出耦合器安装在基板上,使得Lo温度不敏感。 优选地,该基材是具有可忽略的热膨胀系数的热不敏感材料; 例如,它可以是Invar TM,Super-Invar TM,ULE TM玻璃,Zerodur TM和熔融二氧化硅。 或者,衬底是热分离的材料,其被温度控制并与增益介质绝缘。 当Lo = Lg时,轴向模式调谐率的幅度大于峰值增益调谐率。 然而,Lo / Lg是固定和设计的,使得轴向模式调谐率与峰值增益调谐率相同。 特别地,激光器优选地包含用于确保单频操作的装置。 对于环形激光器,它可以包括在腔内的磁体和半波片,与具有反平行布鲁斯特面的棒状增益材料耦合。 对于非平面环形振荡器,半波片的目的是由非平面路径提供。 或者,谐振器是光学参量振荡器。

    • A splicing device is disclosed wherein the conductor and steel support cable portions of an aerial drop wire are each spliced utilizing a single device which is electrically insulated and weather-resistant and has a central member and end caps separable therefrom. The ends of the steel support cable are joined together by a wire linking device integrally molded in the central body and the conductors are spliced together by button-blade terminals driven into conductor-receiving cavities within the same body becoming locked in place. The risk of environmental damage is eliminated by the end caps which protect the stripped portions of the conductors, as well as by the unitary body construction of the central member which provides a sealed environment for the splices themselves.
