The invention belongs to the technical field of non-classical optics, and discloses a non-classical light field generator with phase self-compensation. The non-classical light field generator comprises a laser, a compressed light field generator, a first phase shifter, a beam splitter, a central controller, a balanced zero-beat detector and a spectrum analyzer; the compressed light field generatoris used for generating a compressed light field detected by the balanced zero-beat detector; an output signal of the balanced zero-beat detector is connected with the spectrum analyzer; an output endof the spectrum analyzer is connected with the central controller; an output end of the central controller is connected with an input end of a temperature controller, is used for changing the crystaltemperature through the temperature controller, finding the double resonance temperature of an optical parametric cavity amplifier according to the output signals of the single detectors at differentcrystal temperatures, and is further used for finding the phase self-compensation temperature of the optical parameter amplifier according to output signals of a single detector at different crystaltemperatures; and is further used for finding the phase self-compensation temperature of an optical parameter amplifier according to the compression degree of a first compressed light field at different crystal temperatures. The non-classical light field generator with the phase self-compensation provided by the invention improves the non-classical characteristics of the light field and can be applied to the field of non-classical light fields.
