Experimental demonstration of a temporal pulse shaping method based on nonlinear chirp [PDF]

open access: yesEPJ Web of Conferences
We present a general temporal shaping method based on spectral phase-only modulation for ultrafast laser sources. We explain the working principle of this technique and use it experimentally to generate a ramp-shaped pulse at the output of a laser source

The Variation of the Linewidths and Amplitudes of Sub-Doppler Resonances of 87Rb D2 Line with Laser Beam Intensity

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2022
The sub-Doppler resonances linewidths and amplitudes depend on the laser beam intensity. The effect of laser beam intensity on the resonance linewidths and amplitudes obtained from different energy transitions of atoms varies from resonance to resonance.
