Coherent Introduces High-Power, UV, Solid-State Laser AVIA 355-23 

Santa Clara, CA — The new AVIA 355-23 from Coherent, Inc. delivers over 23 watts of Q-switched output at 355 nm, making it the most powerful all-solid-state UV laser currently available. Based on the popular AVIA platform, this laser sets a new price/performance benchmark, delivering 15% more power than previous models and supporting higher pulse repetition rates. For end users, this improved performance translates into faster processing times and a lower cost per part.

The AVIA 355-23 features short pulse duration, excellent beam quality and high pulse-to-pulse energy stability — all factors that contribute to superior precision and uniformity in materials processing applications. This new laser also supports repetition rates of up to 300 kHz, making it compatible with high-speed systems, such as those utilizing raster scanning. The laser's frequency-tripling component now has a projected lifetime of providing stable output power for more than 22,000 hours. And the AVIA's product reliability is backed up by an industry-leading, two-year warranty.

The AVIA 355-23 is the ideal tool for high-throughput micromachining applications, such as dicing and scribing silicon and low-K semiconductors, as well as via-hole drilling in printed circuit boards and flip chips. Other applications include solar cell micromachining, chip singulation and direct patterning of thin films. The AVIA 355-23 is fully RoHS-compliant, as required by key end-users in Europe and Asia.
