Industrial laser developer Coherent announced a new Monaco industrial ultraviolet (UV) femtosecond laser with 50 W of output power. The company says that the new laser, the first 50 W 400 fs UV laser with proven 24/7 industrial-grade performance, is ideal for high-speed, high-volume cutting of stacked-OLED displays.
This laser is used to cut the OLED displays after they are fully produced, which is why Coherent uses the term stacked-OLED (it does not refer to an OLED display with a stacked - or tandem - emitter design). The laser cutting enables shapes, notches and holes. Coherent updates that it installed over 800 Monaco laser systems worldwide (not all at OLED display fabs, though, the Monaco systems are also used in other applications).
The Monaco 345-25-50 delivers pulses with energies up to 25 µJ at repetition rates up to 2 MHz in the UV with a pulse width below 400 fs. It includes all the standard functionality of the Monaco platform, including pulse-on-demand, variable pulse width tuning, variable repetition rate, and flexible seeder burst mode. Based on its compact size and true single-box design, it is easy to integrate into tools.
