Embodiment Construction

[0037] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0038] 1. Preparation of Polymer Matrix Solid Dye Laser Media

[0039] 1.1 Materials required for the preparation of polymer-based solid dye laser media

[0040] Matrix material: methyl methacrylate (MMA)

[0041] Polymer monomer MMA can form polymethyl methacrylate (PMMA) through polyaddition reaction. PMMA has the advantages of good optical uniformity and high transmittance in the visible light band and dye laser band. The structural formula of MMA molecule is as follows figure 1 shown.

[0042] Laser dyes: PM567, C 440.

[0043] PM567 belongs to pyrromethene (pyrromethene) dyes, which were successfully developed by Boyer and his collaborators in the late 1980s and early 1990s. Its relative molecular weight is 318.22, and its structural formula is as follows: figure 2 shown.

[0044] PM567 has very superior performance:

[0045] (1) It has e...

Abstract

The invention provides a preparation method of a high performance solid dye laser medium. A dye PM567 with the concentration of 5*10<-5>mol / l to 2*10<-3>mol / l, and the concentration ratio between PM567 and C440 is 1:0 to 1:10; the concentration of an initiator is 0.1g / l to 1.5g / 1; the laser dye is mixed with MMA, added with an initiator AIBN, and ultrasonically stirred to lead the dye to be wholly dissolved in MMA; the mixed solution is subpackaged into clean dry test tubes, the test tubes are filled with dry nitrogen to remove oxygen in the test tubes, and finally sealed up and placed into a thermostatic waterbath; when the sample is completely solidified, the prepared solid dye laser medium is taken out from the test tubes. The PM567 polymeric laser medium prepared by the invention has high efficiency, and overcomes the shortcoming that the existing PMMA based solid dye that is only doped with PM567 has poor light stability, and further enhances the performance of polymer based solid dye laser medium.

Description

(1) Technical field [0001] The invention relates to optical technology, in particular to a laser medium. (2) Background technology [0002] Dye laser has the advantages of wide wavelength tuning range, high output power, easy control of absorption and gain, and is the most important tunable laser source. Compared with other lasers, the biggest advantage of dye lasers is that the laser wavelength can be continuously tuned in a wide range and the laser energy can be guided into a narrow spectral line without significant loss. In addition, the dye laser medium of dye laser can be used in solid phase, liquid phase or gas phase, the concentration is easy to control, and it has strong adaptability to various applications. Therefore, dye lasers have broad application prospects in scientific research (spectroscopy), medicine (tissue optics, diagnosis, treatment) and other fields. [0003] In terms of spectroscopy, the dye laser is an ideal light source in classical spectroscopy, a...
