Abstract:

The possibility of construction of a macroscopic source of radiation with decreased natural fluctuations (squeezed light) based on a laser with intracavity generation of the second harmonic is validated.
It is shown that the dip in the photocurrent power spectrum below the shot noise level in the course of detection of frequency-doubled light exceeds the corresponding value for the primary wave by a factor of four.
