| Description
| - In the work, we present a method for direct measurement of the refraction index of air. We designed two coupled glass cells (one evacuated and the other filled by atmospheric air) inserted to plan-parallel Fabry-Perot resonator (F. P. resonator). Two tunable single-frequency lasers pass laser beams through the evacuated and aired cell simultaneously. Two F.-P. resonators are built up by this way: one of them in evacuated cell and the other in the open air cell. If both lasers are tuned along the resonant modes of F.-P. resonators, an optical frequency difference between two adjacent modes can be identified for each resonator. The evacuated one will have another mode-to-mode difference than the aired resonator. With knowledge of these values we can determine the index of refraction very fast.

- V práci prezentujeme metodu přímého měření indexu lomu vzduchu. Navrhli jsme dvě paralelní skleněné kyvety (jedna trvale evakuovaná a druhá obsahující testovaný atmosférický vzduch), které jsou vloženy do planparalelního Fabry-Perotova rezonátoru. Dva laserové svazky dvou laditelných jednofrekvenčních laserů pak prochází přes tyto dvě kyvety. Takto jsou vytvořeny dva optické rezonátory, z nichž jeden je ve vakuu a druhý v atmsoférickém vzduchu. Jestliže jsou lasery laděny podél rezonančních modů rezonátorů, díky frekvenčnímu směšování těchto dvou laserů jsme schopni zjistit frekvenční rozdíl mezi vybranými rezonančními mody obou rezonátorů. Ze znalosti tohoto frekvenčního rozdílu jsme pak schopni určovat hodnotu indexu lomu vzduchu velmi rychle. (cs)
