A new method for fabrication of optical microspheres with the use of a CW CO2 laser is reported. Conventional method for fabrication of microspheres includes grinding and polishing processes which is not only time consuming, but also difficult of getting optical spheres with diameter less than 500 μm. It will be demonstrated that the laser method is very simple and capable of producing a wide range of optical spheres with diameter of several millimeters down to 10 micrometers or even less, and a wide range of materials can be used (glasses, porous glasses, glass-like ceramics...). Some applications of microspheres produced by the laser method are discussed.
