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.

The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
solar cell
A device for converting sunlight into electrical energy, consisting of a sandwich of P-type and N-type semiconducting wafers. A photon with sufficient energy striking the cell can dislodge an electron from an atom near the interface of the two crystal types. Electrons released in this way, collected at an electrode, can constitute an electrical current.
