Santa Clara, Calif. – Coherent Inc.'s new HighLight FAP 60/810 system, a fiber-delivered, turnkey diode laser system that provides 60 W of output power at 810 nm, also utilizes a unique modular fiber delivery system that minimizes downtime and cost of ownership in harsh industrial environments or with semi-skilled labor.
Specifically, the 15 meter delivery fiber is attached to the laser source via standard connectors, meaning it can be quickly exchanged if it is damaged. System value is also increased by an integrated monitor that immediately shuts down the diode if it detects back-reflected light, minimizing the risk of diode damage.
This system is engineered to deliver good reliability, convenience, and process uniformity for demanding, high-throughput industrial applications such as FRIT welding of OLED displays and other thermal processing tasks. In particular, the system offers good output characteristics, such as high power stability (power variations < ±1%) and a fast, jitter-free risetime (< 50 microsec). In addition, an optional four-lens imager enables variable magnification and a top hat irradiance profile at the work surface.
A typical thermal processing application for the system is FRIT welding of OLED screens for smart phones. These screens are created as a glass-OLED-glass sandwich in large panels, and the laser is used to fuse the front and rear glass plates together prior to device singulation. The top hat profile available from the laser is particularly valuable here because it eliminates the possibility of peripheral material damage. Other typical applications include soldering and plastic welding.
