Large-power dual-output external cavity narrow linewidth laser easy for mass production

Abstract

The invention relates to the technical field of lasers, and discloses a large-power dual-output external cavity narrow linewidth laser easy for mass production, which includes a heat sink; a positioning groove is formed in the front surface of the heat sink; a laser chip is fixedly installed at the left end of the front surface of the heat sink, positioning frames located at the top end and the bottom end of the positioning groove are fixedly connected to the front surface of the heat sink, a self-focusing lens located in the positioning groove is fixedly connected into the positioning frame,and a limiting plate located on the right side of the positioning frame is fixedly connected to the front surface of the heat sink. The invention discloses the large-power dual-output external cavitynarrow linewidth laser easy for mass production. The collimating adjustment of the output light of a laser chip is greatly optimized, the feedback light direction adjustment of the laser is greatly optimized and a secondary focusing process after re-collimation in the external cavity light path design is omitted, so that in the whole light path, all optical elements do not need to bear too high energy density, heating deformation cannot be caused, and the light path supports high light power output.

Description

technical field [0001] The invention relates to the technical field of lasers, in particular to a high-power dual-output external-cavity narrow-linewidth laser that is easy to mass-produce. Background technique [0002] Except for free electron lasers, the basic working principles of various lasers are the same. The indispensable conditions for generating laser light are particle number inversion and gain greater than loss, so the essential components in the device have excitation (or pumping) There are two parts, the source and the working medium with a metastable energy level. The excitation is that the working medium is excited to the excited state after absorbing external energy, creating conditions for realizing and maintaining the particle population inversion. The excitation methods include optical excitation, electrical excitation, and chemical excitation. And nuclear energy excitation, etc., the metastable energy level of the working medium is to make the stimulated...
