Under thermodynamic equilibrium conditions, almost all atoms or molecules are in the ground state and so it requires more than half of this number to be excited out of the ground state to achieve laser action. This implies that a much larger pumping input would be required to exceed population inversion threshold. 1, record 1, English, - population%20inversion%20threshold

Cette technique ayant pour but de déterminer un seuil d’audition pour chaque fréquence, on commence, pour une fréquence donnée, par un son d’intensité assez élevée. On diminue ensuite progressivement l'intensité jusqu'à ce que l'enfant hésite ou cesse d’appuyer sur la manette.

The laser gyro need not be mechanically dithered. The same result may be achieved by optical devices. A Faraday cell is a piece of crystal, which changes the phase of a light wave traveling through it as a function of an applied magnetic field. The effect is nonreciprocal. A light beam traveling in one direction is advanced in phase, while a light beam traveling in the other direction is retarded in phase. Reversing the magnetic field reverses the effect. Changing the phase of the light beam has the same effect on frequency as changing the path length.

[...] si le rayon de Larmor de la particule est tel qu’il existe des valeurs de l’angle pour lesquelles la relation (3.16) est vérifiée, la particule subira alors une déflection qui fera varier son angle d’attaque, entraînant du même coup une déviation de sa trajectoire originelle. Le processus alors engagé amènera la particule à rencontrer d’autres résonances qui entraîneront alors une marche au hasard pour la particule. Cette marche au hasard est la base du processus diffusif qui veut qu’une particule perde rapidement le souvenir de sa trajectoire initiale. L’exemple présenté ici est évidemment simpliste (la relation 3.16 n’est pas [toujours valide]). Néanmoins, dans le cas des champs magnétiques chaotiques à trois dimensions, l’idée de résonance reste. Ainsi, il faudra que la particule suive une relation similaire à (3.16) pour qu’elle rencontre des résonances avec le chaos. Si le rayon de Larmor d’une particule est très inférieur (ou supérieur) à la plus petite longueur d’onde du champ chaotique, elle ne subira pas d’effets de diffusion spatiale ou angulaire. 3, record 14, French, - cheminement%20al%C3%A9atoire

A light beam traveling in one direction is advanced in phase, while a light beam traveling in the other direction is retarded in phase. Reversing the magnetic field reverses the effect. Changing the phase of the light beam has the same effect on frequency as changing the path length. This scheme eliminates the vibration problem, but retains the random walk angular position error. 1, record 16, English, - random%20walk%20angular%20position%20error

Les composés minéraux ou organiques qui possèdent des propriétés optiques non linéaires sont de plus en plus utilisés dans des domaines variés, comme les télécommunications, le traitement de données, l'énergie, etc. Ils servent à modifier la fréquence d’une onde électromagnétique et permettent par exemple de transformer une lumière rouge en lumière bleue.
