    Notes: Abstract Frequency stabilization to the gain profile of an internal mirror He−Ne laser emitting at 543.5 nm wavelength is described. The dependence of the power and polarization on frequency was investigated for multi-mode and two-mode operation. The emitted laser modes are linearly polarized. Two orthogonal eigenpolarizations fixed to the laser tube were observed. Spontaneous switching between these polarizations occurred when the laser frequency was scanning through the gain profile. In two-mode operation, these polarization flips have been suppressed by applying a weak magnetic field transversal to the gas discharge. Under such operation conditions the frequencies of the laser could be stabilized to the gain profile by controlling the power difference of the two modes to zero. The fractional frequency reproducibility is in the region of Δf/f≃3×10−8.

    Notes: Abstract Integrating window management capabilities into general purpose graphics systems like GKS or PHIGS is still an open issue. The main integration strategies depending on the responsibility for resource management, are discussed. The GKS* approach takes the graphics system as client of a window system distributing the resources. Its main idea is to introduce user-initiated dynamic resource distribution into the graphics system's model, which is a fundamental deviation from the philosophy of existing graphics standards. Furthermore the inuut model of GKS* has to be extended for running a graphics system in an environment with shared input devices between different application processes. CR Categories and Subject Descriptors: I.3.2.[Computer Graphics]: Graphics Systems—utilities and standards; I.3.6.[Computer Graphics]: Methodology and Techniques—interaction techniques.
