Lamb dip laser
Tīmeklis1990. gada 1. jūn. · The linewidth of the OG Lamb-dip showed a linear dependence on the gas pressure and was independent of the discharge current, as illustrated in fig. 3: we did not see any frequency shift due to these variations, however, since the stability of the laser (a) Fig. 2. Lamb-dip signals of 10 P ( 30 ) observed with 3f detection: (a) … TīmeklisTo fine-tune the frequency of the laser, a diode laser with a piezoelectric transducer that controls the cavity wavelength can be used. Due to photodiode noise, the laser frequency can be swept across the transition and …
