Abstract
The spectral emission of a mid-infrared diode laser at 10 mu m is inve stigated by two different techniques. The fringes of a high finesse co nfocal etalon and the beats with a stabilized carbon dioxide laser are recorded. The conjugate effects of electronic frequency stabilization by using low-pressure gas molecule absorption and the controlled opti cal feedback in an external cavity are shown. The linewidth is reduced from 65 to 20 MHz. (C) 1998 Elsevier Science Ltd. All rights reserved .
