preparation example Construction

[0055] like Figure 5 In some examples, the preparation method can include: solve the fluorescent substances in organic compounds to obtain the first mixture (step S10); add a polymerous cause to the first mixture to obtain solid state media (step s20); polish and and Polishing solid -state medium to obtain solid -dye laser gain medium (step S30).

[0056] In some examples, fluorescent substances can be n, n'-dual (2,6-diopenic benzenel) -3,4,9,10-苝 苝 甲 在 (苝 orange 240). In this case, the glowing peak of 4 Orange 240 is between 570nm-580nm, and 苝 Orange 240 has good light stability and thermal stability. By using 苝 Orange 240 as fluorescent substances can help improve the gain medium stability.

[0057] In some examples, the solid substrate can be an organic polymer. In some examples, organic polymers can be made by organic compound polymerization. In other words, solid -state substrates can be obtained by organic compound aggregation.

[0058] In some examples, organic compounds c...

Embodiment 1

[0084] First, prepare solid -dye laser gain medium:

[0085] Use cylindrical molds with a diameter of about 1cm in the bottom surface and about 0.5cm in height. Use deodorded water, acetone, ethanol for ultrasonic cleaning in turn, and put the mold into a 60 ° C constant temperature oven for drying treatment. Place 1mlmma in a cup, add 0.001mmol (ie 0.71mg) 苝 orange 240 to MMA, heat the water bath at 60 ° C until it is completely dissolved; then add 1 mgbpo, stir at 0.5h, and inject the cylindrical column -shaped after mixing. In the mold, it is placed in a dry box with a temperature of 60 ° C. After the drying 24H, the mold is removed and removed the solid state. The sandpaper is used to polish the solid -state medium.

[0086] Then, the solid -state dye laser gain medium obtained by the Practical Example 1 is tested. The specific test items are as follows:

[0087] (1) Under room temperature conditions, the wavelength of the solid -dye laser gain medium of solid -dye dyeing in t...

Embodiment 2

[0093] Use cylindrical molds with a diameter of about 1cm in the bottom surface and about 0.5cm in height. Use deodorded water, acetone, ethanol for ultrasonic cleaning in turn, and put the mold into a 60 ° C constant temperature oven for drying treatment. Place 3mlmma in a cup, add 0.003mmol (that is, 2.13mg) 苝 orange 240 to MMA, heat the water bath at 60 ° C until it is completely dissolved; then add 3mgbpo and stir at 0.5h. Divide the solution into 3 samples of 1ml each, add 90 μL of methanol, ethanol, and acetone, and stir at 0.5h. After stirring, it is injected into the cylindrical mold after drying and placed in the temperature of 60 ° C at 60 ° C. In the drying box, after the drying 24h, remove the solid -state medium, use sandpaper to polish the solid state, and use the velvet cloth to polish the upper and lower bottom surface of the solid -state medium. Gain medium and third modified solid -state dye laser gain medium.

[0094] Then, the first modified solid -state dye la...

Based on the present disclosure, a solid-state dye laser gain medium and a preparation method thereof can be provided.

Description

Technical field [0001] This public involves a solid -dye laser gain medium and its preparation methods. Background technique [0002] Laser is a device that can emit laser. Among them, dye laser is a laser that is dissolved with dyes in a solvent as a activated medium. Its harmonious performance is excellent and the price is low. However, there are also disadvantages such as the short life of the activation medium, the complexity of the laser structure, and difficulty in maintaining. [0003] Unlike ordinary dye laser, solid dye lasers usually add appropriate laser dyes to appropriate solid substrates. Compared to liquid dye laser, organic dyes in solid dye laser are relatively isolated in solid matrix, reducing the interaction between dye molecules and solvent environments, so it simplifies its research on the physical characteristics of optical physical characteristics and optical non -linearity. For example, it can eliminate the various opposite sexes caused by liquid flow in ...
