Paper Abstract

Distribution of equal laser power into numerous optical fibers is often required for optical sensors, correlation optics, and related metrology. To do so some optical elements have been usually adopted in extracavity scheme. In this paper we shall propose a novel method to couple an equal lasing power into multioptical fibers into intracavity configuration. Mounting numerous optical fibers on the donut-shaped window of a coupling mirror of laser resonator by setting its transmittance at the optimum value, we can extrat the lasing power equally into optical fibers with in phase. As an example of experimental demonstration the numerical calculation will be given for a combination of a CO2 laser and AsS IR fiber.
