AVIA 532-45 from Coherent, Inc. is a powerful diode-pumped, solid state green laser that delivers diffraction-limited output. This laser is said to provide 45W of average power (at 120 kHz) at 532nm, in a single mode output beam (M2 < 1.3). The combination of high power, high repetition rate and excellent mode quality make this laser an ideal source for precision micromachining applications that require both high throughput and precision edge quality (minimized heat affected zone), such as singulation of QFN, FBGA, and µSD (MMC,) as well as direct chip attach (DCA) type packages.
The AVIA 532-45 incorporates the same high-precision pulse control features found in lower power AVIA models. These include the proprietary PulseEQ and ThermEQ, respectively for constant pulse energy over time and uniform pulse energy when the laser is operated in burst mode. These enhance process consistency and flexibility by providing the ability to regulate the energy delivered to the work surface without any change in beam parameters. Coherent, Inc.
