High Power Nanosecond UV Laser Cutting Frosted Glass
High power nanosecond UV laser cutting frosted glass
First, a brief introduction to high-power nanosecond UV lasers. Nanosecond ultraviolet laser is a device that uses high-energy laser pulses to process the surface of materials. Its pulse width is usually between a few to tens of nanoseconds. Its working wavelength is usually in the ultraviolet band, with higher photon energy and better beam quality. This kind of laser is widely used in various material processing fields, such as glass, ceramics, metal, etc.
Secondly, the principle of cutting frosted glass with high-power nanosecond ultraviolet laser is explained. Frosted glass has high surface roughness and scattering properties, which causes the laser energy to quickly attenuate and scatter on the glass surface, resulting in inefficient and uneven cutting. However, by using a high-power nanosecond ultraviolet laser, local point-like heating can be generated on the surface of the frosted glass, and the overall cutting of the glass can be achieved with the help of heat conduction inside the glass.
Finally, the technical details of cutting frosted glass with high-power nanosecond UV laser are described. During the cutting process, parameters such as laser pulse width, pulse energy, beam shape, and scanning speed need to be precisely controlled to ensure cutting quality and efficiency. In addition, the auxiliary gas flow rate and gas type during the cutting process will also affect the cutting effect. Adopting appropriate process parameters can effectively improve cutting efficiency and reduce breakage rate.
In summary, high-power nanosecond UV lasers have unique advantages in cutting frosted glass. However, further research on process optimization and equipment performance improvement in actual production is still needed to achieve wider application and promotion.
