ОДНОЧАСТОТНЫЙ HE-NE ЛАЗЕР

摘要

FIELD: engineering physics; manufacture of single-frequency stabilized gas lasers. ^ SUBSTANCE: proposed laser has resonator formed by mirrors that accommodates active element and frequency selector in the form of Fabry-Perot etalon whose faces are made at angle to plane perpendicular to laser axis and disposed at distance r = L/n from resonator output mirror to front face of Fabry-Perot etalon, where L is resonator length; n is number of resonator longitudinal modes within amplification line contour; Wo is least diameter of beam in resonator. ^ EFFECT: enhanced power and stability of single-frequency emission mode due to reduced resonator loss. ^ 1 cl, 2 dwg
