Coherent releases high-contrast marking lasers for consumer goods


Coherent has released its Matrix nanosecond pulsed UV lasers for high-contrast marking applications in consumer goods, industrial electronics, home appliances, and packaging.

The new Matrix UV lasers are diode-pumped solid-state lasers that provide superior marking quality at half the entry price of existing solutions, the firm says. 

Dr Christopher Dorman, Senior Vice President, Solid-State Lasers Business Unit, Europe, said: “We believe that the market for the next-generation ultralow-cost Matrix will expand quickly, driven by the demand for more environmentally sustainable alternatives to adhesives, inks, and labels for high-contrast marking of plastics.”

The new Matrix lasers are available with 5W and 10W output power and operate at a pulse repetition rate ranging from 50kHz to 300kHz. The lasers can achieve more than 15,000 hours of maintenance-free operation, enabling reliable high-volume production, according to Coherent. 

The Matrix lasers can output up to 200µJ of pulse energy at 355nm and are based on Coherent’s UV technology.
