Prisma Laser
Dec 2007
Coherent Inc.Request Info
SANTA CLARA, Calif., Dec. 28, 2007 -- Coherent Inc. said the latest addition to its Prisma series of all-solid-state infrared and green lasers offers the highest output power available to date. Specifically, the new Prisma 1064-20-V is a Q-switched, Nd:YVO4 (neodymium doped yttrium orthvanadate) laser that delivers 20 W at 1064 nm. With 25 percent higher output power than previously available, this laser enables faster throughput or reduced processing times, while still lowering the cost per watt.

Specifically, the new model shows excellent transverse mode quality (M²<1.3) and high pulse-to-pulse stability (<2% rms from 40-100 kHz), while enabling complete control over pulse-energy and timing. The laser uses field-proven AAATM-material pump diodes and is factory-sealed for high reliability, even when operating in harsh, industrial environments.

Together, all these features make the Prisma 1064-20-V an ideal source for a variety of marking and materials processing applications, Coherent said. These include ID card marking and keypad marking, as well as solar cell or mold-form manufacturing.
