Diffractive variable attenuator for femtosecond laser radiation control.

We present a diffractive phase variable attenuator for femtosecond laser radiation control. It allows the control of beam power up to 0.75.

Polar coordinate laser pattern generator for fabrication of diffractive optical elements with arbitrary structure.

A precision laser pattern generator for writing arbitrary diffractive elements was developed as an alternative to Cartesian coordinate laser/electron-beam writers. This system allows for the fabrication of concentric continuous-relief and arbitrary binary patterns with minimum feature sizes of less than 0.6 microm and position accuracy of 0.

[Optimization of cardiovascular function by peptide bio-regulators].

Effects of peptide bioregulators (thymaline, epithalamine, cortexine) on systemic hemodynamics in cardiovascular and cerebrovascular affections were studied. Assessment of functional stability and quality of cardiovascular system regulation was made according to methodological principles of automatic regulation theory. Peptide bioregulators showed high effectiveness in the above patients who markedly improved their hemodynamic parameters.
