Original Press Release:
New Laser Delivers Power and Beam Quality for Singulation and Other Micromachining Applications
Santa Clara, Calif., November 30, 2007 - Coherent, Inc. (Santa Clara, CA) (Nasdaq: COHR) has introduced the AVIA(TM) 532-38, a diode-pumped, solid state laser which delivers over 38 W of output at 532 nm (at 120 kHz) with a pulsewidth of only 45 nsec. This laser's excellent beam characteristics (TEM00, M² < 1.3), combined with its high average power and high peak power, make the AVIA 532-38 the optimum tool for micromachining applications requiring both fast throughput and precision edge quality (minimized heat affected zone). Applications include singulation of microelectronics packages, wafer scribing, and edge isolation in solar cells.
Backed by a 2 year/10,000 hour warranty, this new model is based on the existing, field-proven AVIA O/A platform (oscillator/amplifier cavity) that is configured for long-term stability, high reliability and ease of operation. This design incorporates key proprietary features such as PermAlign(TM), a solder-bonding technology for securely mounting all the resonator optics, as well as long-lived AAA(TM) (Aluminum-free Active Area) pump laser diodes. The laser is simple to operate and integrate thanks to the use of Total Pulse Control, a comprehensive software suite that enables customized pulse control and power on demand. The complete AVIA 532-38 laser system includes a sealed, water-cooled laser head and a compact air-cooled power supply.
