Coherent introduces 50W UV Femtosecond laser for cutting SiC wafers and stacking OLED displays

Coherent, a leader in industrial lasers for materials processing, today announced the introduction of a new industrial ultraviolet (UV) femtosecond laser, the Monaco, with an output power of 50 W, ideal for high-speed, high-volume wafer cutting and stacked OLED displays.

The rapid growth of applications such as wafer slotting and display stack precision cutting for mobile and next-generation chips has accelerated the demand for laser tools with higher output power that can process such materials at high speeds and with high precision.

The Monaco 345-25-50 is the first 50W 400 fs UV laser with industrial-grade performance, enabling high-precision cutting and perfect assembly fit.

The laser delivers pulses with energies up to 25μJ, a repetition rate of up to 2 MHz in ultraviolet light, and a pulse width of less than 400 fs. It includes all the standard features of the Monaco platform, including pulse on demand, variable pulse width tuning, variable repetition rate, and flexible planter burst mode.

Allan Ashmead, senior vice president, Microelectronics and Instrumentation, Coherent North America, said: "Our Monaco 345-25-50 is the latest addition to our highly successful Monaco Industrial laser platform and represents the smallest 50 W femtosecond laser on the market. The Monaco product line is field-proven, with more than 800 systems installed in facilities around the world, operating 24/7, for mass production of medical devices as well as OLED displays for leading consumer applications."

Following the recent introduction of the new high-power and high-energy Monaco 1035-150-150 infrared laser, the Monaco 345-25-50 will further expand Coherent's portfolio of Monaco infrared and green lasers. The entire Monaco series can be cut through direct ablation of various wafer materials, including silicon carbide wafers.
