Abstract
A measuring system is described for the phase determination of a microscopic radiation field. The essential element of this system is a Q-switched Nd:YAG laser which serves as an ideal laser amplifier with a high amplification of approximately 1010, having insignificant quantum noise. The result for a phase measurement of several photons (about five) is presented.
