Coherent has unveiled its latest product, the Monaco 345-25-50. This new ultraviolet (UV) femtosecond laser stands out due to its 50 W output power capacity, making it well-suited for high-speed, high-volume cutting operations, particularly in the wafer and stacked OLED display industry.
The emergence of new applications like wafer grooving and precision cutting for advanced IT and mobile devices has led to an increased demand for high-power lasers. These tools need to deliver speed and precision to cater to such applications. The Monaco 345-25-50 is the first of its kind machine with 50 W 400 fs UV laser capability. This technology ensures precision cutting at very high volumes, enhancing the efficiency of assembly processes.

The Monaco 345-25-50 distinguishes itself with features like pulse-on-demand, variable pulse width tuning, variable repetition rate, and a flexible seeder burst mode. Moreover, it delivers pulses with energy levels up to 25 µJ at repetition rates up to 2 MHz in the UV spectrum, and has a pulse width of less than 400 fs. The new laser’s compact, single-box design makes it simple to integrate into existing tool sets. It complements Coherent’s Monaco product line of infrared and green lasers including the recently relaesed Monaco 1035-150-150 listed above for comparison.
