Device and method for producing coherent bi-color light source

摘要

A device for producing a coherent bi-color light source, including: an array substrate, a first laser tube driven by a first direct current signal, a second laser tube driven by a modulation signal coupled by a microwave signal and a second DC signal, a half wave plate, a birefringent crystal, a first quarter wave plate, a partially reflecting plane mirror, and a second quarter wave plate. The first laser tube and the second laser tube are fixed on the array substrate. The half wave plate, the birefringent crystal, the first quarter wave plate, the partially reflecting plane mirror, and the second quarter wave plate are disposed in sequence in an emission direction of a laser beam emitted by the first laser tube. The second laser tube is disposed opposite to the birefringent crystal.
