established range of integrating spheres, designed to measure total radiant power and luminous flux of lamps, luminaires and large LED modules. The sphere offers the same capabilities as its smaller peers, making it is particularly suitable for testing solid-state lighting (SSL) products as well as conventional lamps and luminaires. The ISP 2000
AuSn hard solder and designed for a wide range of aerospace, defence and industrial applications. Also on display were a variety of
new products designed to meet the needs of medical applications. These high power IR (2-5W) devices are packaged in a modified TO can and incorporate an integrated, single mode, red pointer diode in the same 9mm housing.

intense showed a number of new high power diode laser products, including its Series 8000 793nm multi-mode pump module. Designed for eye-safe, thulium- doped fibre laser systems, these multi emitter modules provide up to 20W of output power from an 105µm core fibre. The company also introduced the high brightness Hermes 650W mini stack, an ultra compact QCW stack with an output in excess of 8kW/cm2
~300µs pulses, and available in 808 and 940nm wavelengths (custom wavelengths and multicolour options on request). The entire Hermes line was on
display, including QCW bars that provide up to 400W of output power, and the QCW 1kW, 2kW, and 3KW stacks. All Hermes bars and stacked arrays incorporate Intense’s quantum well intermixing (QWI) technology, which increases the brightness and reliability of the lasers while reducing instances of catastrophic optical damage. These bars and stacks are assembled using

laser Zentrum hannover presented examples of green photonics at the show, including the use of laser technology for light- weight construction, for regenerative energy production, as an alternative to environmentally harmful processes, as well as new energy- efficient laser systems. For example, LZH laser technology can be used for processing CFRP materials (carbon fibre reinforced plastics). This technology is instrumental in innovative light-weight concepts for the aeronautical and automotive industry. Expensive and costly raw materials can be reduced and the use of fuel can be lowered. LZH laser technology is also important in the production of regenerative energy. In this field, lasers can be used for welding glass tubes for higher quality solar receivers, or for increasing the energy efficiency of photovoltaic cells.

Furthermore, the LZH presented new fibre components, which can be used in energy efficient fibre laser systems for material processing, or for medical technology, including a newly-developed, ultra-short laser oscillator based fully on fibre lasers. This oscillator can be employed for treating presbyopia.

optek systems, a supplier of laser processing and micromachining equipment and services, presented the LaserCleave, a compact, production-ready tool for non- contact optical fibre cutting for optical connector and component
manufacturing. The LaserCleave eliminates mechanical scribing, which can cause fibre chips and hackle, and also reduces the need for polishing steps in order to meet GR-326 (Telcordia) compliance. The device is robust and small enough to be integrated into a production line. The LaserCleave range also consists of tools for cleaving simplex connectors, bare fibres, and multi- fibre connectors, including ribbon fibre, and compliments OpTek’s established optical fibre processing tools.

spi lasers, part of the Trumpf group, launched four new products at the show, including a redPower branded fibre laser with between 500W and 1kW output, and a new 500W fibre laser in the R4 product family. The redEnergy brand has been further developed to include the next generation fibre laser platform, G4, which includes fibre lasers in the 10-70W power range, building upon the company’s popular G3 MOPA range. A green pulsed laser will also be introduced in the company’s redEnergy range. SPI’s high power OEM fibre laser systems offer integrators the capability to manufacture
JpsA introduced its IX-6168 micromachining system at the show. The flexible system allows users to integrate different laser modules, such as Lumera’s Super Rapid, in order to adapt to various micromachining requirements. The system can be configured with either excimer, DPSS, or picosecond lasers for large area patterning or direct write processing. Also on display was the company’s IAP system, which provides
equipment for cutting and welding applications in the industrial macro sector with scalable output powers. The lasers allow the integrator the ability to differentiate their product by customising the optical and electronic control interface performance and functionality for the specific application. Design features include thermal management, high output power stability, and power and temperature monitoring with an optical resonator.

toptica presented lasers for a multitude of exciting applications. In focus were biophotonics, quantum optics, terahertz and test and measurement.
The display featured a new multi- laser engine (iChrome MLE) with up to four different wavelengths, designed for microscopy and cytometry. From the company’s broad portfolio of scientific diode lasers, it showed a narrow-band CW system with 2W at 589nm – with an example of what the lasers do to a group of Rb atoms. Active coherence control (BlueMode) opens new possibilities in industrial inspection applications. Also presented were two highly compact and cost effective sources for THz generation: a CW-laser at 1.5µm (TeraBeam) with fibre-pigtailed antenna modules, and a fibre-based fs-laser (FemtoFErb) ideally suited for time- domain THz.
