Abstract
The invention provides a process for preparing a solid state dye laser in a composite glass matrix, without the use of polymerization initiators, comprising preparing a porous silica gel, effecting thermal treatment thereof at a temperature of at least 500.degree. C. to produce a glass with improved mechanical properties, impregnating a solid state laser dye dissolved in methylmethacrylate into the silicon gel glass in a closed container and effecting heat polymerization of the methylmethacrylate at a temperature of at least 60.degree. C., whereby there is formed a glass having pores impregnated with a solid state laser dye and polymethylmethacrylate.
Claims6
A process for preparing a solid state dye laser in a composite glass matrix, without the use of polymerization initiators, comprising:
- a) preparing a porous silica gel;
- b) effecting thermal treatment thereof at a temperature of at least 500.degree. C. to produce a silica gel glass of sufficient strength to undergo impregnation with a laser dye solution;
- c) impregnating a laser dye dissolved in methylmethacrylate into said silica gel glass in a closed container;
- and
- d) effecting heat polymerization of said methylmethacrylate at a temperature of at least 60.degree. C., whereby there is formed a solid state final glass product having pores impregnated with a laser dye and with polymethylmethacrylate.
