Abstract

The invention provides a preparation method of a colloidal quantum dot continuous laser. The preparation method comprises the steps that composite luminescent material of the perovskite quantum dot material and the polymer is formed on the corresponding surface of a resonant cavity through an in-situ method to act as gain medium. The invention also provides the colloidal quantum dot continuous laser comprising the gain medium which is used for receiving photons excited by continuous laser radiation; and the resonant cavity which is combined with the gain medium and used for amplifying the photons excited by the gain medium so as to output continuous laser, wherein the gain medium is the composite luminescent material of the perovskite quantum dot material and the polymer prepared through the in-situ method.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to a colloidal quantum dot continuous laser and a preparation method thereof. Background technique [0002] Semiconductor continuous lasers have the advantages of small size, light weight, long life, and simple integration. They have important application values ​​in the fields of laser radar, laser medical treatment, laser display, laser lighting, material processing, and communication. The number of particles at each energy level of the continuous laser and the radiation field in the cavity have a stable distribution, and the excitation of the working material of the laser and the laser output can be continuously performed in a continuous manner within a long period of time. [0003] In 1971, Alferov et al. proved that semiconductor continuous lasing can be realized in double heterojunction lasers. Since then, semiconductor continuous lasers have experienced several important deve...
