Abstract

We investigate photon statistics in the signal beam generated by frequency nondegenerate parametric downconversion both with and without a seed field along the idler direction. The experiments are performed on the signal generated in β-barium borate by a traveling-wave pump pulse that is the frequency-tripled output of an amplified Nd:YLF picosecond laser. The high powers obtained allow us to measure the number of photons with a simple detection technique. When both signal and idler fields are initially in their vacuum states, the generated fields are mixtures of equally occupied modes with thermal photon-number statistics.

Figures (4)

Fig. 1.
Fig. 1.

Layout of the experimental setup. The outputs (fundamental, ω ; second-harmonic, 2ω ; third-harmonic, 3ω) of the picosecond amplified Nd:YLF laser serve as: pump (3ω); an idler seed when necessary (ω); synchronous trigger (2ω) for the measuring apparatus via the photodiode, PD. BBO I is a nonlinear crystal with type I interaction. Lens LB focuses the signal cone reflected by BBO I onto the S monitor (photodiode monitoring the signal-cone energy). The blank at the LB center is actually a small mirror reflecting the pump reflected by BBO I onto the P monitor (photodiode monitoring the pump-pulse energy). The animation shows photographs of the signal cones striking the wall of the laboratory (see text for details). [Media 1]

Fig. 2.

Photon detection probability distributions as a function of channel number x for different ND filters on the signal at 2ω [optical-density (OD) values of the ND filters are indicated]. Experimental data, solid curves; numerical fits, vide infra. The inset shows the mean channel number, X, of the experimental distributions as a function of ND-filter transmittance, i.e., 10-OD; straight line, least-squares fit. For conversion to photon numbers: n=(Δq η)x, with Δq=78125 electrons/channel; see text.

Fig. 3.

Photon detection probability distributions in the signal at 2ω as a function of channel number x for spontaneous downconversion (open circles) and for downconversion with a seed idler pulse (filled circles). Square symbols, distribution for X=0. Inset, logarithmic plot of the data for spontaneous downconversion and best-fitting Gaussian with a fixed mean value corresponding to the experimental X value. For conversion to photon numbers see Fig. 2 with Δq=34393 electrons/channel.
