Embodiment 1

[0021] Using the method in this example, the original dark red gold-doped glass can be completely erased and selectively erased partially or form a colorless pattern inside the glass. The steps are as follows:

[0022] First, the colorless and transparent composition is: 70SiO 2 20Na 2 O 10CaO 0.01Au 2 O (mol%) gold-doped glass is heat-treated at 550°C for 30 minutes to make it discolored as a whole, showing dark red and basically opaque;

[0023] Then use a 120fs laser (wavelength: 800nm, pulse repetition frequency: 1000Hz, average power: 50mW) to converge inside the glass sample through a 10x lens, and scan a selected area;

[0024] Finally, the glass sample scanned by the femtosecond laser was heat-treated at 300° C. for 30 minutes, and the area scanned by the femtosecond laser was colorless and transparent. The colorless and transparent range corresponds to the range of previous laser irradiation or scanning.

Embodiment 2

[0026] Using the method in this example, the appearance and erasure of red color and its cyclical changes can be realized at selected positions inside the original colorless and transparent glass sample.

[0027] 1. At first, use a femtosecond laser (parameters such as embodiment 1) to converge in the colorless and transparent glass sample composed as embodiment 1 through a lens of 5 times, and scan a certain selected area;

[0028] 2. Then heat-treat the glass sample scanned by the femtosecond laser at 520°C for 30 minutes, and the glass sample will appear red in the area scanned by the femtosecond laser;

[0029] 3. Then use the femtosecond laser to scan the red area, and then heat treatment at 300°C for 30 minutes, the red color disappears, and it becomes colorless and transparent;

[0030] 4. After continuing to heat treatment at 500°C for 30 minutes, the red color appears again;

[0031] 5. Repeat steps 3 and 4 to realize the cyclic change of red appearance and erasure. ...

Embodiment 3

[0033] Using the method in this example, the appearance and erasure of the yellow color inside the glass can be realized.

[0034] The composition of the glass is: 70SiO 2 20Na 2 O 10CaO 0.01Ag 2 O (mol%) silver-doped glass, and adopt the same method as embodiment 1 and embodiment 2, can realize the operation of another kind of color (yellow) appearing and erasing equally. The experimental operation and phenomena are the same as those in Example 1 and Example 2 except for the two points described below. First, corresponding to the red in the first two examples, this example is yellow; second, the coloring heat treatment temperature in Example 2 is 520°C, and the coloring heat treatment temperature in this example is 450°C.

Abstract

The process of forming color inner carving inside glass includes the following steps: converging super-short pulse laser beam with micro objective to selected position inside glass sample while proper micro objective and laser irradiation condition is selected to obtain required laser spot size; moving the platform with glass sample set via computer control and controlling the on-off of laser beam with electronic shutter to form designed shape and pattern with the laser focus inside the glass; and performing heat treatment of the glass after laser irradiation, with the temperature for heat treatment being controlled for fading and development of the formed pattern.

Description

technical field [0001] The present invention relates to a method for modifying three-dimensional color engravings inside glass, specifically, a method for selectively erasing and modifying three-dimensional color engravings formed inside glass by using an ultrashort pulse laser. Background technique [0002] In the "method for forming internal coloring and three-dimensional color patterns of transparent objects" (Chinese patent application number: 00127613.1), we use ultrashort pulse lasers, and use laser-induced ion valence changes, color center formation, and nanoparticle generation to achieve In order to engrave colorful three-dimensional patterns into the inside of the glass, the artistic value of glass inner carving crafts is improved. However, the above invention patent only involves the coloring process inside the glass, and does not mention the removal process of the colored color. If the erasing of the painted color and the modification of the engraved three-dimens...
