10. Stimulated emission in pulsed PDC was also considered by F. De Martini [Phys. Rev. Lett. 81 (1998) 2842] for a different purpose, namely the generation of Schrödinger cat states. In the meantime, first experimental results have been presented (V. Mussi, F. De Martini: in Proceedings of III Adriatico Research Conference on Quantum Interferometry, Trieste. March 1999, to appear).
