Coherent Company has developed an industrial ultraviolet femtosecond laser with an output power of 50W, which can perform large-scale wafer cutting

Coherent has developed an industrial ultraviolet (UV) femtosecond laser with an output power of 50 W that is ideal for high-speed, high-volume cutting of wafers through direct ablation, including silicon carbide and stacked OLED displays.

Rapid growth in applications such as wafer slotting for mobile and next-generation chips and precision cutting of display stacks is accelerating the demand for laser tools with higher output power that can process materials at high speeds with high precision.

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

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

"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," said Allan Ashmead, senior vice president, Microelectronics & Instrumentation, North America.

"The Monaco product line is field-proven, with more than 800 systems installed in facilities around the world, operating 24/7, 7 days a week, mass-producing medical devices as well as OLED displays for cutting-edge consumer applications.

The Monaco 345-25-50 expands Coherent's infrared and green laser product line in Monaco and follows the recent launch of the new high-power and high-energy Monaco 1035-150-150 infrared laser.
