Intense Ltd., developer of next generation semiconductor lasers, systems and solutions, today announced the new Series 2400 eye safe laser diodes at World of Photonics 2009 in Munich. The Series 2400 are 1550nm short pulsed single emitters and stacks that have been redesigned for higher power and efficiency. The single emitters are available in 75µm to 150µm junction lengths, with power levels of 6W to 12W. Individual emitters can be stacked in...

NEC Electronics Europe has introduced a series of uncooled 1310nm Multiple Quantum Wells (MQW) structured Distributed Feed-Back (DFB) laser diodes allowing the operation up to 95°C and low power consumption. The NX8346-series transmitter optical sub-assembly (TOSA) is based on a new AlGaInAs chip design allowing high temperature and high speed operation. Due to an oxidation free BH-structure, low operating currents (Iop) and high reliability are...

Intense Ltd., developer of next generation semiconductor lasers, systems and solutions, today announced at Photonics West an expanded range of high power QCW bars and stacked array products. The new Hermes Stacked Array line now includes higher power QCW laser diodes, ranging from 600 to 3,000W, qualified to MIL-Standards. In addition, Intense provides passively mounted QCW Bars with power levels ranging from 100 to 400W.

Renesas Electronics announced the company’s first blue-violet semiconductor laser diode with a wavelength of 405 nm and a new structure incorporating an optical waveguide into the semiconductor device, which enables high power output and excellent suitability for mass production.

Power Integrations today announced a reference design kit for a 150 W, 48 V power supply for LED streetlights and other industrial/infrastructure lighting systems. The driver circuit described in RDR-292 is more than 93% efficient at 230 VAC input and above 91% at 110 VAC. The design delivers a system power factor of greater than 0.97, THD of less than 10%, and easily meets EN61000-3-2 C. Designs can be scaled from 75 W to 400 W, using the same p...

Marl International has invested £150,000 to double its manufacturing output at its site in Ulverston Cumbria, putting it in a prime position to benefit from the rapid growth of an emerging ‘green’ lighting technology. The line has been specially modified to handle PCB boards of up to 600mm long, much more than the standard length. Such boards are commonly required to replace conventional lighting products. The announcement brings the investm...

ProPhotonix Limited is pleased to announce that they are adding the HL65051DG laser diode from Opnext, Inc. to the wide range of diodes ProPhotonix offers. This new laser diode gives system designers and OEMs the highest power single-mode laser on the market at this wavelength in a package that includes an integrated monitor photodiode.

EV Group today announced the EVG620HBL Gen II - the second generation fully automated mask alignment system for volume manufacturing of high-brightness light-emitting diodes (HB-LEDs). Introduced one year after the launch of the first-generation EVG620HBL, the Gen II delivers a tool platform tailored to address HB-LED customer-specific needs and the ongoing demand of total cost-of-ownership reduction. The EVG620HBL Gen II also optimizes tool foo...

EV Group announced that it has signed a joint-development and licensing agreement with Eulitha AG, a pioneer and leader in the production of high-quality nanostructures using advanced lithography techniques. EVG will integrate Eulitha's PHABLE mask-based ultraviolet (UV) photolithography technology with EVG's automated mask aligner product platform with the goal of developing a low-cost-of-ownership (CoO) nanopatterning solution to enable the pr...

LASER COMPONENTS is pleased to introduce the LabSource series of bench top laser sources manufactured by PD-LD Inc with Volume Bragg Grating stabilised laser diodes. Two models are available; the LS-1 with a single Volume Bragg Grating stabilised laser diode, and the LS-2 featuring two stabilised sources. Wavelength stability is +/- 5pm over 8 hours with a +/-0.5% power stability over the same period.
