(Top panels in (a–c)) Schematic diagram of the relative position between collection wavelength (red dashed rectangle) and lasing wavelength shift range.
Dotted resonances depict the cold-cavity resonance wavelength and solid resonances the stationary wavelength for a given photon flux. Bottom panels in (a–c) detail the observed line-shape of the time-resolved signal under three different wavelengths of detection: (a) at λc ≈ λini, (b) at λini < λc < λs and (c) at λc ≈ λs. Notice that Δt1 < Δt2 < Δt3.
