Active stabilization of a carbon dioxide laser with a diffraction selector

Abstract

Using the φ-mapping method, we argue that ferromagnetic spin-triplet superconductors allow the formation of unstable magnetic monopoles. In particular, we show that the limit points and the bifurcation points of the φ-mapping will serve as the interaction points of these magnetic monopoles.

Conventional CO 2 Gas Laser With High-Stability Of Output Beam

“…This solution is very simple and assures a relatively high stabilization factor. 3,4 The choice of such a method of power stabilization makes it possible to avoid additional losses of the output energy, when -as in our case -the zeroth -order output beam of the grating is, included in the stabilization loop.…”

“…The above factors participating in the population inversion mechanism cause simultaneously casual changes of the output power occuring in time. Typically, in conventional CO2 gas laser the frequency fluctuations range within 10-6 -10 -7 for the averanging time equal to 1 s, and peak -to -peak changes in the output power are within 15 minute periods approximately equal to 1-10% or more.1, 2,3 There is a sort of CO 2 discharge laser applications in which the output beam with stabilized parameters is requred. Stabilization of the output beam parameters is possible only when additional automatic control systems are used.…”
