  • Publication number: 20160149377
    Abstract: An optoelectronic oscillator for generating an optical and/or electric pulse comb, comprising a monolithically integrated passively mode-coupled semiconductor laser and an optical feedback loop which guides a part of the optical radiation of the semiconductor laser and feeds said part back into the semiconductor laser as feedback pulses. Without the influence of the feedback pulses, the semiconductor laser would emit comb-like optical pulses, hereafter referred to as primary pulses, and in the event of an influence, emits comb-like output pulses which have been influenced by the feedback pulses, said output pulses having a lower temporal jitter or less phase noise than the primary pulses. The feedback loop is damped between 27.5 and 37.5 dB, and the time lag of the feedback loop is selected such that each feedback pulse is incident within the temporal half-value width of each subsequent primary pulse.

  • Publication number: 20150307824
    Abstract: In a clarification method for a beverage liquid, in particular for producing beer, the beverage liquid, after it passes through a fermentation stage, is subjected to a clarification which serves for removing active haze components from the beverage liquid, and fed to a maturation vessel in which the beverage liquid is stored for a maturation time. In a further method step, the beverage liquid is charged with at least one pectin-containing clarification agent for increasing a filtration performance. In this case it is provided that the pectin-containing clarification agent is introduced into the beverage liquid on the path from the fermentation stage to the maturation vessel and the pectin present therein, before the feed to the maturation vessel, is at least for the most part removed again from the beverage liquid.
