Abstract: Increased light output results from certain design modifications in a GaAs infrared emitting diode coated with a phosphor for converting this emission to visible light. These design modifications include shape and dimensional considerations for minimizing internal reflection and absorption of infrared emission within the diode as well as dimensional and compositional considerations as applied to the coating for reducing scattering losses and minimizing internal reflection of its emission.

Abstract: A crystal of KTax Nb1-x O3, where x lies between 0.2 and 0.8 is produced by said crystal growth from a melt at 1250 DEG C in an oxygen containing atmosphere. Initial ingredients may be in the form of oxides or carbmates, and small quantities of Sn, Si, Ge and Ti may be added as dopants. Care is taken to minimise the presence of Ca, Cl, F, Sr, Ba, Na and Li.
Abstract translation: 通过在1250℃的熔体中在含氧气氛中的晶体生长，产生了X在0.2和0.8之间的KTax Nb1-x O3晶体。 初始成分可以是氧化物或碳酸镁的形式，并且可以添加少量的Sn，Si，Ge和Ti作为掺杂剂。 注意使Ca，Cl，F，Sr，Ba，Na和Li的存在最小化。

Abstract: Q-switching of a laser is accomplished by controlling the state of an intracavity acousto-optic switch that comprises a piezoelectric transducer bonded to a low-optical-loss ultrasonic propagation medium. Energization of the transducer causes a traveling acoustic diffraction grating to propagate through the medium. Illustratively, the direction of propagation of the grating is perpendicular to the direction in which light travels in the laser. The interaction between the light and the acoustic grating gives rise to diffraction losses that prevent the laser from oscillating. In response to a momentary deenergization of the transducer, the laser cavity is restored to a high-Q oscillatory condition during which energy stored in the system during the nonoscillatory state is suddenly released. During each such deenergization period, a high-amplitude output pulse of coherent radiation is obtained.
