specific Embodiment approach 1

[0009] Embodiment 1: The preparation method of the modified polymer matrix solid dye laser medium in this embodiment is as follows: 1. First, wash the methyl methacrylate three times with a NaOH solution with a mass concentration of 5% to 10%, and then wash it with distilled water Methyl methacrylate until the washing liquid is neutral, then carry out vacuum distillation of methyl methacrylate; 2. Methyl methacrylate and hydroxyethyl methacrylate treated in step 1 are mixed according to the ratio of 1.5 to 9:1 The volume ratio is mixed to obtain mixture A, then add ethanol to mixture A, and ultrasonically stir for 15min to 30min to obtain mixture B, the volume percentage concentration of ethanol in mixture B is 10% to 20%; 3. Add PM567 dye to mixture B , and then ultrasonically stirred for 10min to 15min to obtain a PM567 dye concentration of 2×10 -4 mol / L mixture C, add azobisisobutyronitrile to mixture C, and then continue ultrasonic stirring for 10min to 15min to obtain mix...

specific Embodiment approach 2

[0011] Embodiment 2: This embodiment differs from Embodiment 1 in that the mass concentration of the NaOH solution in Step 1 is 8%. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0012] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that in step 2, methyl methacrylate and hydroxyethyl methacrylate are mixed at a volume ratio of 2-8.5:1 to obtain mixture A. Others are the same as those in the first or second embodiment.

Abstract

The invention discloses a preparation method of a modified polymer substrate solid dye laser medium, and relates to a preparation method of a laser medium, which solves the problem of short service life (poor light stability) of liquid dye in the solution state. The method comprises the following steps of: 1. treating methyl methacrylate; 2. preparing a mixture B; 3. preparing a mixture D; and 4.solidifying a mixture D, and annealing and machining the solidified mixture D to obtain the modified polymer substrate solid dye laser medium. The slope efficiency of the output characteristic curve of the modified polymer substrate solid dye laser medium is 31.7-43.2%.When the volume percent concentration of ethanol in the mixture B in the step 2 in the preparation process is 10%, the light stability of the modified polymer substrate solid dye laser medium reaches the highest, the output is only lowered to be 84.5% of the initial output after pulse pumping 100 thousand times, and the corresponding normalized light stability is larger than 25GJ / mol.

Description

technical field [0001] The invention relates to a preparation method of a modified polymer matrix solid dye laser medium. Background technique [0002] Since the appearance of lasers in 1960, tunability has been an important part of laser research. The core of a tunable laser is a tunable laser medium with a broadband energy level structure. Traditional dye lasers work in liquid form. Although liquid dye lasers have some advantages, liquid dyes have a short lifespan (poor photostability) in a solution state. Due to the large volume of the circulating cooling system caused by liquid dyes, it is necessary to replace and clean the defects of the circulating system containers and pipes regularly, so that the liquid dyes Lasers are very inconvenient to use. Moreover, dye solvents are often toxic, flammable and explosive, endangering people's health and safety. Contents of the invention [0003] The purpose of the invention is to solve the problem of short lifespan (poor pho...
