Abstract: A compact wavelength monitoring and control assembly for a laser emission source is provided comprising a narrow bandpass, wavelength selective transmission filter. element, of Fabry-Perot etalon structure, through which a non-collimated beam-from the laser source is directed onto two closely spaced photodetectors.  For wavelength, stabilization, the differential output of the two photodetectors is used in a feedback loop to stabilize the wavelength of the laser source to a desired target wavelength.  Through the angular dependence of the wavelength transmission of the Fabry-Perot etalon, a wavelength variation from the source is converted to a transmission loss, which is different for the two photodetectors, so that the wavelength change is detected as a differential power change.  The device functions as an optical wavelength discriminator in which the detector converts optical energy to current for a feedback loop for controlling the light source.  A lens may be used to control the divergence of the light incident on the filter element to optimize power transfer.  Optionally, wavelength tunability is provided by changing the angle of inclination of the Fabry-Perot etalon relative to the laser source. The system is compact and may be co-packaged within the same package as a laser emission source, overcoming coupling, space and power dissipation problems common with known external semiconductor laser wavelength control units.

Abstract: Un amplificateur à commande automatique de gain (12) amplifie des signaux MF émis par une tête vidéo (11) à une amplitude fixe, et un amplificateur générateur de crêtes variable (15) dans la bande latérale inférieure génère des crêtes sur la bande latérale inférieure des signaux MF. Un filtre (18) pour bande latérale inférieure extrait la bande latérale inférieure de la sortie de l'amplificateur (15), et un circuit de détection (19) de crêtes convertit l'amplitude de la bande latérale inférieure extraite en une tension de courant continu. Un comparateur (20) compare la tension de courant continu à une tension de référence et extrait une tension d'erreur. La tension d'erreur est réinjectée dans l'amplificateur générateur de crêtes (15) de façon à rendre constant le rapport, d'une part, de l'onde fondamentale des signaux MF à démoduler et, d'autre part, de la bande latérale inférieure. L'amplitude de la bande latérale inférieure des signaux MF est par conséquent maintenue constante et est réglée de sorte que le rapport signal/bruit et la résolution soient bons et que l'image soit nette.
