Metal particle manipulation by laser irradiation in borosilicate glass

We propose a new technique of manipulating a metal particle in borosilicate glass. A metal particle that is heated by laser illumination heats the surrounding glass by radiation and conduction. A softened glass enabled metal particle migration. A 1-µm-thick platinum film was deposited on the back surface of a glass plate and irradiated with a green CW laser beam through the glass. As a result, the platinum film was melted and implanted into the glass as a particle. Platinum particles with diameters of 3 to 50 μm migrated at speeds up to 10 mm/s. In addition to platinum particles, nickel and austenitic stainless steel (SUS304) particles can be implanted.

As a result, the platinum film was melted and implanted into the glass as a particle. The glass around the platinum particle heated by the laser illumination was softened, which enabled the platinum particle migration in the glass. Platinum particles with diameters of 3 to 50 µm migrated at the speeds up to 10 mm/s. In addition to platinum, nickel and austenitic stainless steel (SUS304) particles was able to be implanted.We propose a new technique of manipulating a metal particle in borosilicate glass.
