FIG. 1.

(Color online) Normalized histograms from simulations with noise in (a) only the pulse energy and (b) only the spectral phase. In both cases the population of the target Rb level decreases from its maximum value when noise of any kind is introduced. In (a) the FWHM of the two-photon diode signal is roughly double the FWHM of the pulse energy, reflective of the second order process, while in (b) any deviation from the optimal phase reduces the diode signal.

Typical temporal history of the two-photon diode signal for the laser system operating in an unstable state. The long-term signal-to-noise ratio (L-T S/N) is determined from the time segment of shown. The inset shows the power spectrum of the two-photon diode noise taken over . The power spectrum was fitted to , and the best fit is shown as the dotted line. The parameters , , and are used to assess the stability of the laser system together with the L-T S/N ratio.

FIG. 3.

Typical temporal history of the two-photon diode signal for the laser system operating in a stable state. See the caption of Fig. 2 for further explanations.

FIG. 4.

(Color online) Simplified view of the laser amplifier. The thick black line indicates the added plastic partition wall, which evidentially prevents thermal air currents arising in the amplifier from disturbing the spatially separated spectral components in the stretcher/compressor. The areas where spectral components are spatially separated are indicated by hatching.
