Abstract

The invention discloses an experimental device for detecting an ODMR spectrum of a diamond NV color center based on a DAC device. A beam expanding lens, a second reflecting mirror, a first reflectingmirror, a focusing lens, ruby and the diamond NV color center are sequentially installed on a light path emitted by a laser device. A focusing lens, a filter lens, a collimating lens and a photoelectric detector are sequentially arranged on a light path of fluorescence emitted by the ruby and diamond NV color center, and the photoelectric detector is connected with a signal collector. The microwave generator is sequentially connected with the power amplifier and the copper wires through SMA port connecting wires; two ends of the platinum wire are connected with copper wires; and the diamond NVcolor center is picked up to be close to the platinum wire. The experimental device for detecting the ODMR spectrum of the diamond NV color center based on the DAC device is simple in structure, anda new choice is provided for detection of the superconducting phenomenon and the like.

Description
