摘要:

The physical characteristics of high resistivity CdTe which are relevant to its use for electro‐optic modulation have been investigated at 3.39 and 10.6 &mgr;. The unclamped electro‐optic characteristicn0 3r41of CdTe was found to be 12 × 10−11m/V and the absorption coefficient is 0.006 cm−1. Our measurements indicate that CdTe will be a very important material for electro‐optic modulation in the infrared.

摘要:

Holographic images covered with range contours were produced by the multifrequency emission of a pulsed ruby. The multifrequency emission arises from the use of a resonant output reflector in the laser cavity, producing contour intervals equal to the optical thickness of the resonator. Intervals of about 1 cm and greater are attainable.

摘要:

It is shown that the low‐power linear behavior of a cavity (here a spherical one) partially filled with plasma plays a fundamental role in understanding the formation of an rf plasma inside it athigher powerlevels. The rf plasma is found to be sustained in one of the linear resonant states of the system. With moderate rf power (10–100 w), it is possible to sustain bounded plasmas in the cavity having densities far above the critical one. The value of the density depends, as is theoretically predicted, essentially on the frequency and only slightly on the power level of the exciting signal.

摘要:

The low‐field microwave emission from InSb subjected to parallel electric and magnetic fields is strongly dependent on the type of electrical contact attached to the sample. It is suggested that the radiation is a localized phenomenon due to high‐field regions or due to a Schottky barrier.

摘要:

Kinetic theory is used to calculate the electron temperature and drift velocity in a continuous argon ion laser discharge. The calculated electron mean energies range from 1.0–7.5 eV, increasing with current density to the ⅔ power. The calculated drift velocities range from ∼1–25 × 106cm/sec. From these parameters, the electron density is obtained at typical current densities: At 500A/cm2the electron density is found to substantially exceed 1015cm−3. Some consequences of these drift velocities and densities are discussed.
