Abstract

The invention discloses a preparation method of a solid laser working substance with dye laser properties, and the solid laser working substance prepared by the method overcomes the critical defect that the laser is large in size and limited to use due to the complex optical path structure of the dye laser; a laser made of the laser working medium is the same as a common solid laser and has the advantages of being simple in structure, small in size and convenient to carry. Pumping is carried out within the range that a pumping light source is 945 nm to 980 nm, green light of 525 nm can be directly generated, and the single-machine continuous laser power can easily reach 40 watts and is about eight times that of an existing mainstream green laser under the same condition. According to the resonant cavity provided by the invention, the sheet is arranged between the first lens and the second lens, so due to a laser manufactured by the resonant cavity, a frequency doubling optical device in a traditional green laser is saved, the structure of the traditional green laser can be simplified, and the light conversion rate of the laser is improved.

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 ...
