Tunable continuous-wave operation of a Cr3+,Li+:Mg2SiO4 laser.

Room-temperature tunable cw laser oscillation of Cr3+ ions in forsterite crystals (Mg2SiO4) codoped with chromium and lithium has been demonstrated, for the first time to the authors' knowledge, in pumping a crystal with a Ti:sapphire laser into the first excited level of Cr3+ ions (4A2-4T2 transition). The laser is smoothly tunable in the region of 1095-1170 nm. A slope efficiency as great as 4.4% has been achieved.

[Analysis of a control system for speech movements].

Analyzing the control quality in autonomic contour of articulation control system an account is made for the nonlinearities of the type of the zone ofunsensitivity, limitation and logarithmic response of the receptor. Regions of stablity and autooscillation frequency are determined. The role of recontrolling value is stated as a criterion of the control quality. It is suggested that the mechanisms of some stammering forms are concerned with the initiation of autooscillations in the articulation control system.
