Abstract

The invention relates to the technical field of lasers, and specifically discloses an alkali metal vapor laser with multi-wavelength output. The alkali metal vapor laser of the invention comprises a pump light source for emitting pump light, wherein the emitted pump light comprises single-photon absorption pump light and two-photon absorption pump light; a coupling lens group for coupling focusingthe pump light; An alkali metal vapor cell for converting the pumping light into a multi-wavelength laser; A temperature control furnace for controlling the working temperature of the alkali metal steam pool; A resonant cavity, arranged corresponding to the alkali metal vapor cell, for realizing multi-wavelength laser oscillation output. The invention provides an alkali metal vapor laser with multi-wavelength output mixed with alkali metal atom single-photon and two-photon absorption mechanism, which can realize multi-wavelength laser output by using single-photon and two-photon absorption mechanism of single alkali metal atom.

Description

technical field [0001] The invention relates to the field of laser technology, in particular to an alkali metal vapor laser with multi-wavelength output. Background technique [0002] In recent years, high-performance multi-wavelength lasers have been widely used in industrial manufacturing, military, medical and scientific research fields. Since the generation of lasers, research and development of multi-wavelength laser sources with high efficiency, high power, and high beam quality has been the direction and goal of scientific research in the laser field. However, at present, multi-wavelength laser light sources usually use multiple laser beams for synchronization and output on the same channel, which has problems such as complex structure, low efficiency, and poor coaxiality. [0003] In recent years, a new type of LD pumped alkali metal vapor laser (Diode-pumped alkali-vaporlaser, DPAL) has attracted more and more attention and research because of its technical charact...
