Industrial Laser enables high-throughput micromachining

The new PRISMA(TM) 1064-32-V from Coherent, Inc. (Santa Clara, CA) is an industrial laser that delivers an optimum mix of high peak power, short pulsewidth, high average power and exquisite beam quality. This is an ideal combination for high-throughput, precision micromachining. In terms of specifications, PRISMA is a diode-pumped, solid-state, Nd:YVO4 laser that produces 30 W at 1064 nm in a TEM00 beam, with a pulsewidth as short as 18 ns, and pulse repetition rates from 20 to 100 kHz.

PRISMA is well suited for micromachining small features in all types of materials because its short pulsewidth results in a minimal heat-affected zone. Typical examples include solar cell processing, mold form manufacturing, deep engraving, and wafer scribing. (For applications that benefit from longer pulses, the PRISMA LP versions are offered.) In addition, the high average power of PRISMA enables these applications to be operated at high-throughput rates.

The new PRISMA 1064-32-V also offers superior reliability and stability, as well as low cost of ownership characteristics, due to its rugged construction, sealed resonator, and use of superior Coherent AAA(TM) (Aluminum-free Active Area) pump diode technology. As with all PRISMA series products, this laser can be readily tailored to precisely match its output characteristics to the needs of a specific application. In addition, PRISMA 1064-32-V is also available with a number of useful accessory options, such as a beam expander, visible aiming beam and mounting flange for scanner optics.
