Abstract

The invention discloses a method for preparing a solid laser working substance with dye laser properties. The solid laser working substance produced by the method of the invention overcomes the complexity of the optical path structure of the dye laser, which makes the laser bulky and limited in use fatal defect; the laser made of this laser working medium is the same as the ordinary solid-state laser, which has the characteristics of simple structure, small size and portability; it is pumped in the range of 945nm-980nm as the pumping light source, and can be It directly produces 525nm green light, and its stand-alone continuous laser power can easily reach 40 watts, which is about eight times that of the current mainstream green lasers under the same conditions; the resonant cavity of the present invention passes between the first lens and the second lens With thin slices, the laser made of this resonant cavity can save the frequency doubling optical device in the traditional green laser. It not only simplifies the structure of the traditional green laser, but also improves the light conversion rate of the laser.

Description

【Technical field】 [0001] The invention relates to a preparation method of a solid laser working substance, in particular to a preparation method of a solid laser working substance with dye laser properties. 【Background technique】 [0002] Laser products can be divided into infrared band lasers, visible band lasers, ultraviolet and deep ultraviolet lasers. Among them, the green laser in the visible light band is the most important and important laser. It is used in precision welding of copper and aluminum in civilian applications, such as copper welding in power batteries and electronic devices. It is also a newly emerging laser display such as laser The necessary light source for film and laser TV, green laser is also the basic light source for ultraviolet and deep ultraviolet laser production (frequency doubling technology). Green laser also plays an important role in national defense and military industry. It is the basic light source of controllable thermonuclear fusion ...
