Velocity-selective double resonance in Doppler-broadened rubidium vapor

Interference effect and Autler-Townes splitting in coherent blue light generated by four-wave mixing

“…This is due to the AT effect caused by the frequency comb mode ω n , but blurred by the other scanning mode. The maximum intensity of the CBL generated in this case occurs when the system meets the double-resonance condition [18]:…”

Quantitative modeling of complex molecular response in coherent cavity-enhanced dual-comb spectroscopy

“…Optical frequency combs (OFCs) [1][2][3][4] enable increasingly precise applications of atomic and molecular spectroscopy [5], including primary thermometry [6,7], optical radiocarbon dating [8], sub-Doppler and Doppler-free spectroscopy [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26], ultrafast and multidimensional spectroscopy [27][28][29][30], survey spectroscopy of molecular ions and cold molecules [31][32][33], and time-resolved spectroscopy for fundamental chemical kinetics [34][35][36][37]. Applied spectroscopies [38] also make novel use of optical frequency combs for actively monitoring greenhouse gas fluxes [39][40][41], methane for open-path detection [42] and unambiguous source attribution [43] and reactive atmospheric species [44], elucidating the chemical composition of combustion and open flames…”

Rate equation reformulation including coherent excitation: application to periodic protocols based on spectral hole-burning

“…Despite a clear motivation to model the hole-burning dynamics in rare earth ion-doped crystals for optical signal processing, our model could certainly be used in other domains where the interplay between coherent evolution and accumulation appear under pulsed excitation. This is the case for multilevel atomic vapors under femtosecond pulses where the internal dynamics is driven by the accumulation of many pulses described by an abundant bibliography [32][33][34][35][36][37][38][39] finding application in optical metrology, or for complex molecules and semiconductor structures whose fast response can be studied by coherent spectroscopy [40]. We first present our method and give the explicit formulation of the steady state in the general case.…”
