Abstract
Calculation of the second order correlation function for light that is a mixture of laser light and chaotic light of the same central frequency has been done by several groups. We have measured the two-photon counting rate in a mixed light beam and have found good agreement with these calculations. Half of the light in this beam originated in a stable single mode 633 nm He:Ne laser, and the other half in a low pressure He:Ne discharge tube. The d.c. discharge tube was about 20 cm long and was viewed end-on. Because the 633 nm Ne transition in a He:Ne discharge shows gain, the tube is a thick source, the line is slightly narrowed compared with a thin source, and the useful intensity is several times higher than any previously available narrow band chaotic source. For reasonable tube lengths, the amplitude distribution from this type of source is expected to be Gaussian.
