Shimadzu Develops Blue Direct Diode Laser for Microfabrication
CompoundSemi News Staff
October 14, 2013...Shimadzu has developed a blue direct diode laser. The 10-W type will be placed on reference exhibit at InterOpto 2013 (October 16th to 18th at Pacifico Yokohama, Japan). The company claims that it is the first blue direct diode laser, which features a microscopic spot size and can be applied to microfabrication
. According to Shimadzu, benefits of direct diode lasers include their compact size, high-efficiency electro-optic conversion, and their ability to be mass-produced at low costs. Shimadzu asserts that, short wavelength, high output semiconductor lasers that work in the visible region where the rate of absorption by metal is high, will enable new machining materials and microfabrication.
Shimadzu claims to have achieved a 16-fold increase in brightness over conventional levels for fiber-coupled blue semiconductor lasers, which feature high rates of absorption by metals. This has been achieved by utilizing newly developed optical multiplexing technology in addition to high-durability coating technology and techniques for precision assembly of optical equipment, cultivated to date, based on GaN semiconductor lasers utilized in Blu-ray Discs and projectors.
The laser features a fiber coupling design that enables a laser beam with high efficiency, even for kW-class output. Shimadzu claims that its power consumption is about one half that of solid-state green lasers. Firstly, a 10-W model will be released in about January 2014. Afterward, the company says it will develop 50-W and 100-W types and spatial output types to enhance the product line.

Sharp and Osram Enter into LED and Laser Diode Patent Cross-Licensing Agreement
LIGHTimes News Staff
August 26, 2013...Sharp Corporation of Osaka Japan and Osram GmbH of Munich, Germany have entered into a patent cross-licensing agreement covering LEDs and laser diodes. Terms of the agreement were not disclosed, and the specific patents covered were also not revealed. The cross-licensing agreement grants each company the right to use inventions related to LEDs and laser diodes covered by the patents around the world, which the respective companies own. Sharp and Osram expect that the agreement will invigorate their Research and development and contribute to further advances in LEDs, laser diodes, and related industries.
Sharp is by no means a new entrant into the LED market. Sharp began mass-production of LEDs in 1970 and claims the world's first production of infrared laser diodes for CDs in 1982. Sharp reportedly built up these LED and laser diode technologies over the years. In addition the Sharp says it has recently come out with numerous unique devices, including a high-efficiency, high-brightness 100 W-class LED for lighting, and a red laser diode that can be used as a light source for displays.

CompoundSemi News Staff
May 13, 2013...Excelitas Technologies’ Surface Mount 905 nm pulsed semiconductor laser is designed specifically for high volume applications such as laser therapy, range finders, safety light curtains and adaptive cruise control. Multi-cavity layers concentrate the emitting source size and create three emitting active areas. When operated at 30A, these areas produce 70W of peak optical output power on average. The laser is mounted on an FR4 substrate, a leadless laminate carrier (LLC), which Excelitas says provides thermal management and power stability. The laser diode is intended for surface mount application and for hybrid integration. The diode encapsulate material is a molded epoxy resin for low cost and high-volume manufacturing.
Osram Coordinating BMBF Project for Infrared Laser Sources
CompoundSemi News Staff
February 22, 2013...As part of the ‘Integrated Microphotonics’ initiative, Osram
Opto Semiconductors is coordinating the IMOTHEB project (integrated
microoptical and microthermal elements for diode lasers of highbrilliance). The
goal is to improve the performance and reduce production costs of laser
systems. The project partners are DILAS Diode Laser and the Max Born Institute.
The project (FKZ 13N12312), which is supported by the German Ministry for
Education and Research (BMBF), runs from October 1, 2012 to September 30,
Osram notes that diode-pumped high-power laser systems for material
processing provide lower operating costs, greater efficiency and smaller size.
Fiber lasers and fiber-coupled diode lasers are becoming more and more
important for optical material processing but are more costly. Therefore
researchers need to improve performance while reducing costs of infrared
semiconductor laser diodes, which can be used to pump fiber lasers.
The project maps the entire value chain from the semiconductor chip to the
complete laser system. The semiconductor lasers, cooling elements, optics, and
sensors will be targets of performance improvement and cost reduction. They
also plan to increase the output of semiconductor lasers by 40 percent by
September 2015, while retaining the same high beam quality.
Simulations are being subcontracted to the Fraunhofer Institute for Applied
Optics and Precision Engineering. DILAS is responsible for the assembly
technology with improved thermal resistance and higher integration in laser
modules, and also for automation in module production. The Max Born Institute
will analyze and characterize the chips and modules.
Modulight Launches 1W RGB LimeLight Laser Modules Claiming Smallest Form Factor
CompoundSemi News Staff
January 28, 2013...Modulight, Inc., of Tampere, Finland and San Jose, California
launched the new version of its LimeLight laser systems that are
half the volume of previous systems claiming it is the smallest RGB
laser solution. The systems produce 1W output power at 635nm, 532nm
and 465nm. It measures just 80mm x 80mm by 40mm. The firm says that
the systems offer a spread of wavelength from visible 465nm to NIR
1550nm and optical output power from 500mW to 30W.
Modulight says its LimeLight laser system platform is ideal for life
science applications as well as display and laser projection. The
system has standard interfaces and integrated control and cooling
solutions for what the company claims is a very low integration
cost. The standard LimeLight systems come with an SMA-905 receptacle
fiber output, integrated driver, a cooling controller, and a smart
on/off switch. Both CW and pulsed operation can be controlled
through an 10-pin connector port by a standard PC user interface or
by an analog/digital control signal directly. The platform also
supports many safety features needed for medical applications, like
pilot beam, fiber interlock, and safety switch.
Mr. Sampsa Kuusiluoma, the New Product Introduction Manager at
Modulight explained that lasers have a wide range of package sizes
for different wavelengths and power levels.
"We decided to fix that with our LimeLight platform that offers
simple unified interfaces for any systems integration despite the
varying device technologies and used package form factors,"
