Nonlocal eigenmode of ion cyclotron range of frequency instability in the presence of parallel high energy beam component is obtained in a toroidal plasma in an inhomogeneous magnetic field. The mode is the combination of the fast wave and Bernstein wave and is excited via kinetic interactions with bean particles. When the driving source of high energy particles overcomes the total dampings due to the bulk plasma and the resistive loss on the wall, the instability can occur. Nonclassicai energy/momentum transfer rates due to this mode between different plasma species are obtained. Nonlocal energylmomentum transport is simultaneously induced. The rate of nonclassical energy transfer reaches ihe classical level at the low level of wave amplitude.

The aging characteristics of transverse-mode stabilized InGaAlP laser diodes at high-power operation above 10 mW have been investigated. A rapid degradation mode related to the inner optical density of the laser was observed. This degradation mode could be effectively suppressed by reducing the inner optical density, adopting an asymmetric facet coating, and with a thinner active layer. Highly reliable operation at a high-power level above 10 mW for more than 1000 hours has been realized.
