Ushio announced the initiation of its new laser diodes mass production. The new products HL67191MG and HL67192MG offer operation at the 670 nm wavelength. Providing an optical output power of 15 mW (CW) and 30 mW (pulsed), these single-mode LDs deliver high-temperature performance (up to 70°C) within a φ5.6 mm package. Both LDs achieve a low operating current of 30 mA at 25°C (15 mW in CW operation) and feature built-in monitoring photodiodes.

Osram Opto Semiconductors has produced a broad area laser diode with a lateral brilliance of up to 4.8 W/(mm*mrad) in the laboratory. The more brilliant the laser, the more efficiently it can inject its light into optical fibers. This then increases the output power of modules for pumping fiber lasers used for material processing. This progress is one of the results of the project “Integrated microoptical and microthermal elements for diode lasers of high brilliance” (IMOTHEB) which was funded by the German Federal Ministry of Education and Research and which has now been successfully completed. 

Leading Japanese LED manufacturer Nichia spoke to Taiwanese reporters about technologies it will be focusing on this year, and about its outlook for 2016, during a press conference held at Palais de Chine Hotel in Taipei, Taiwan on Thursday.

SoraaLaser, a world leader in commercialization of visible laser light sources, will present its innovative light source technology at Strategies in Light conference, March 1-3, in Santa Clara, CA. These advanced light sources feature unique performance properties such as collimated output and waveguide delivery, and provide compelling advantages over LED, OLED, and legacy sources in specialty lighting.

Many types of laser diodes (LDs) were displayed at OPIE’15, which took place last month in Yokohama, Japan. LD can be classified into gas laser, YAG lasers, semiconductor lasers, quantum cascade lasers and others.

With its SPL BF98-40-5 laser bar Osram Opto Semiconductors has succeeded in combining power and beam quality like never before. Thanks to its high brilliance, the laser diode considerably reduces the complexity of coupling light into fibers. Diode or fiber laser systems for material processing can be made simpler and therefore more cost-effective. Even at its maximum output of more than 60 watts the component has an impressively long life.

Last October, the biologist and former GE Healthcare chief scientist James Rothman received the Nobel Prize in Physiology and Medicine for solving the mystery of how cells shuttle molecules of insulin and other substances to the right place in the body. This year, two other former GE scientists looking for new sources of light, Bob Hall and Nick Holonyak Jr., almost felt the glow of a Nobel themselves.

Nichia Corporation, headquartered in Tokushima and directed by President Eiji Ogawa, announced today its decision to commercialize blue and green semiconductor laser diode models specifically designed for automotive Head-Up Display (HUD) systems*1 .

For the first time there is a compact laser multi-chip package. Osram Opto Semiconductors can pack up to 20 blue laser chips in the new PLPM4 450 module. Instead of taking the laborious approach and constructing a light source from individual laser diodes, it is now possible to reduce the complexity of laser projectors significantly. Developers also succeeded in doubling the optical output of the individual chips, with the result that the new laser module now offers an overall output of 50 W. This means that professional laser projectors can achieve a brightness level of more than 2000 lumen with only one component.
