Novalux announced that it has rolled out the new Necsel lasers that are ideal for applications such as direct scan projection and microdisplay projection. The Necsel lasers are low-cost, high-power laser light sources and come in wavelengths of 640, 532, and 465 nm. The lasers are also offered as an integrated RGB laser.
Necsel Laser
The Necsel lasers are gallium indium arsenide (GaInAs) semiconductor lasers featuring extended cavities to manage both optical mode and wavelength. The extended cavity allows Necsel lasers to offer a single mode beam that combines with small mode area fibers adequately. The design allows the lasers to deliver performance similar to solid-state lasers.
The Necsel lasers have the ability to offer output powers (in the region of a watt) in single-mode operation. They also have beam diameters in several microns, which is greater than the conventional VCSEL designs. A coupling efficiency of 90% is obtained with single-mode optical fiber. Over 85% of coupling efficiency is obtained with multimode optical fiber.
The lasers operate in temperatures ranging from -20°C to +75°C. The laser devices, available from Pacer, are anticipated to have a substantial impact on medical instrumentation, electronic theatre, digital video, lighting, displays, and telecommunication applications.
